I find this law quite good.
You'll see your flexible phone as the peak device for 5 years, then again will come the right to repair and battery issues.
Perhaps your point could be that there needs to be a process to get an exception from this law for a year or two if the committee wants to help some technically chalenging devices. But expecting all makers to do the right thing by themselves is unrealistic (and no, "voting with your wallet" doesn't help when a set of brand dominate a market and collude on the issue)
Changes were driven by market forces.
If they came up with easier to recycle designs I'd hear you, but the only industry I see having done real efforts is the plastic bottling industry, and it is still hands down one of the worse plastic producer, even considering recycling.
In the meantime it'd prevent needlessly thin phones and laptops designed around planned obsolescence.
It's hard not to see this sort of regulation at the very least slowing down innovation and causing worse environmental outcomes as a side effect over a decades long scale. It won't be apparent to most people though, since they won't be able to see the counterfactual world where technology improved slightly faster.
It just sounds like a generic antiregulatory complaint ungrounded in reality? It's not like li-ion tech has advanced dramatically absent such regulations. The bottleneck seems to be chemical, a matter of energy density, not a regulatory chokehold on innovation.
It's just part of a bigger right-to-repair war, whether it's batteries or cars or operating systems. Manufacturers are increasingly moving to rent-seeking behaviors and X as a subscription, which is great for their profits but not so good for consumers or societies.
Big tech is already on the verge of supplanting governments across the world, the last thing they need is more freedom to "innovate". They don't do it for the social good, just for their profits, and regulation is always playing catch-up to try to limit the social and environmental damage from their actions. At least the regulations have some measure of democratic buy-in, vs the what, 2-4 big tech companies that alone determine the future of tech? They don't have your interests at heart, at all.
One place this is seen is building regulations. It's not uncommon for an exact door or frame thickness to be legislated, and the required thickness is based on fire risks. This was a very good thing in the short term, but in the longer term, it removed any economic incentive for innovating new materials that require less thickness to provide the same level of protection.
Since it's been many decades since regulations were created in most places, there's often quite a bit of low hanging fruit, from a materials technology standpoint. There would be even more if the rules had targeted objectives (e.g. fire resistance), as opposed to methods (e.g., a set material thickness).
In the big scheme of things, technological progress has been strongly correlated with social good. We live longer, healthier lives and have more amenities than any time in history. It's much nicer to be living in the 2020s than I would be in the 1970s, 1920s or the 1820s. People living in each of those earlier eras saw the benefits they had from electricity, antibiotics, rail transportation, etc that those before them lacked and it's not hard to imagine people in the 2070s will be happy not to be saddled with our current level of technology.
It's easy to devalue what we don't yet have, but it's a fallacy.
Sure, a lot of technology has proven socially useful, but usually with regulation (of natural monopolies, for example) and subsidies and such. It's not an either or situation. Companies can and do profit alongside mandatory social contributions that they otherwise would not have done if it meant more profit.
In the electronics space, things like safety regulations, charging standards, warranty protections, etc. have hurt profits but been good for the consumer. There's a balance.
Still, there are valid reasons to make more integrated devices and it's not reasonable to expect everything to be as easy to service as it becomes more advanced. My father could take apart and rebuild all kinds of car engines in the 80s and 90s, but would never be able to do that with a Tesla. It was still a great thing for Tesla to drag the auto market kicking and screaming into an age of electronic vehicles, though.
About electric cars though, case in point, they are a market that people have been clamoring for right to repair on. Not necessarily so they can hack the firmware themselves, but so that they can take it to their local mechanic for repairs instead of the dealership. I understand there is something of a cottage industry of places that can service some Priuses and Leafs etc but some newer cars are too locked down for third parties. That's essentially a DRM thing and hampers innovation in the post sale services sector, anticompetitive OEMs who want to prevent cheaper third party components.
