Really the main difference is that Apple has a captive audience on iOS and no incentives to improve so they don't do anything with it.
It is a magnitude higher.
So instead of "10x" substitute "by a large enough factor or margin to make a significant difference". That is totally true globally speaking. Locally, in the US, you could however argue that apple abuses it's iPhone market share to sabotage competition (e.g. streaming, webstandards,etc). That just means you should sue both not neither.
The easy fix is to make them slow down development, but I fail to see how that's a good thing.
For a more practical example, Linux is also developed mostly by paid employees, but they are from many different companies and thus improvements can't be weaponized as easily.
Or they could do what Brave, Vivaldi and others do and simply use Chromium as a base.
Don't you even see the problem?!
Even Microsoft dropped out from developing a web browser, it literally has a larger scope than a whole OS.
But sure, enjoy your Chrome OS proprietary "open" web.
Not sure if you remember all the "native" applets that actually were proprietary before Chrome came on the scene and made JS fast enough to kill them... ActiveX, Flash, Java... Those were the dark ages, because of Google the web is more open and better than ever...

It's a lot more than just Google...
my ad-blockers ruin plenty of websites. never met a site that was broken due to FF itself.
It’s not, other than Google has a way larger market share (especially if you count Edge/Opera/Brave/etc.) and has been (ab)using that position to push web standards in a direction that favors their business and that other browser vendors have to follow to keep up.
If Safari had Chrome’s market share and was throwing their weight around like Google does and Microsoft did with IE, it’d be the same argument and I’d also personally support forcing them to divest it.
