Honestly that's just wishful thinking. Generally these monopolies, regardless of 'artificial propping up' tend to be fairly natural monopolies and these sorts of changes just make it harder on people to get the experience they had before and prefer.
I recently got a couple of new windows laptops and Edge defaulted to Bing, but after changing away from Bing it is relentlessly trying to make me set Bing as the default search engine every few days.
Note that I am using Edge here, not Chrome. Last time I installed Chrome I think it forced me to pick a default search engine, and didn't endlessly harass me to pick Google as its default (I use duck duck go)
I don't see how they could break up Google without forcing MS and Apple to also be broken up too since they're doing the same things with forcing Edge/Bing and Safari on everyone.
Edit: Windows is 73%, closest is Mac OS at 15% (which was way higher than I expected) https://gs.statcounter.com/os-market-share/desktop/worldwide...
what should be happening is that the provider of the maps app is nothing to do with google search and then if your favorite map provider can plug-in to the search results in a seamless way it wouldn't be an anti-trust issue at all. it would benefit all parties. instead google opts to, and who can expect different, maximize the annoyance to their already captive users and minimize their negative business impact (e.g. sending anyone to somebody else's map app).
but they certainly aren't going to voluntarily break themselves up because some regulation that can be implemented in a way that's annoying to their users. who still have no viable other options, btw.
the root cause of the annoyances the users are now facing is both caused by googles monopolistic behavior in the first place and then them weaponizing their own captive users to push back on any regulations trying to stem it. a significant contributing factor is regulations like these are do more harm than good.
the right answer for abusive monopolies is to 1) don't let them form and 2) break them up when they do. chicken-shit regulation like this will only have the predictable result - avoidance, annoyance, no-real-change. and, as you alude, simply make everything worse for everyone.
If I make an aggregator aggregator, should I be able to demand placement on Google search results above mere aggregator sites?
