I think it's up to other browsers to offer better solutions.
The main reason Chrome became so dominant is because:
* Google search results nagged all users to install it for a better experience
* bundled Chrome with countless free software downloads
* it is the default browser on Android
If I leave that box checked, it does use a web view that is "Powered by Firefox", but I always prefer to have it just open a new tab in my regular Firefox app.
Yes, users could be clueless and be trading personal privacy unwittingly but that's not what I mean about "serves users very well". I meant users look at Chrome, Firefox and others and stick to Chrome. If they didn't like Chrome, they would switch.
By your book might makes right, because Google was able to push users to convert in various ways - some of which should be or even are illegal - and it worked for them they must be delivering something that people need. But it wasn't a free choice.
