"worse" is debatable, but they certainly are an issue.

However, that doesn't make it ok in Firefox either. Having a good reputation does not mean you can burn it away by trying your best to look the same as the bad guy you're supposed to fight. Firefox mobile, for a very plain and simple example, have stuff like "future experiment" and telemetry enabled by default. Sure, I can disable them, but they should either be disabled by default, or have a one-time popup that provides the option on the first launch.

My position is that if a piece of software becomes increasingly intrusive and tedious to use with each "update", it's time to look somewhere else. Whether it's Firefox, Chrome, or even OS like Windows. Having to fight back to get to a decent, usable state means that it's no longer the right tool for you.

Fortunately, some people are doing the heavy lifting by providing what would be considered "vanilla" firefox with some good forks, as far as being a browser goes.
