Hard to imagine that what he did (in order to repair a single copy) doesn't have a massively greater negative environmental impact than obtaining a mass-produced replacement. Unless this were done at scale, it would probably be counter-productive.
My prediction is that in the majority of cases we'd have slightly bulkier, slightly costlier devices, many likely a bit more prone to damage because of things like less effective seals or connectors failing, and that 1% of users would actually repair them. Probably a net negative in terms of environmental impact.
Years ago there was a push especially in Europe to install dual flush toilets that allow you to perform either a less-water flush. Many years later we find that due to these more complicated mechanisms being just slightly more prone to malfunction, the net impact is actually more water being wasted.

I'd suspect a similar sort of situation here.
When you're talking about doing "repairs" on modern electronics, almost always you're really talking about replacing entire modules containing hundreds/thousands/millions of these "components" with a replacement either directly from the manufacturer or designed to be compatible it. These modules need to be intentionally designed to a much greater degree, the manufacturer then needs to allocate extra space for this, decide what components will be located on each module, how many modules to break the design into, provide connectors that are both secure during normal use while also being easily connected/disconnect by users, and maintain a supply chain for each replaceable module long after the design is no longer being manufactured. It's a lot more work than the vast majority manufacturers have ever done (with the exception of auto manufacturers).
