They allowed google to push them around on some key things:

- no addons on mobile for more than a decade! for nothing other than google-told-them-not-to.

- moving to webextensions because "google have a better standard for cross browser extensions". Broke all extensions for a long time and google did not honor their promise from day one (e.g. try to install flutter debug extension on firefox)

- reverting features on devtools for no good reason or explanation (e.g. try to change code or update a variable value after hitting a break point on the debugger.)

- No decent search on bookmarks. they keep adding and removing the keyword field. etc.

- marketing. Like it or not, it is the reason badly informed people here, right next to this comment, claim it is slower. lol. marketing lies but it matters. q.e.d.
