Not necessarily, if you kept your filters and extension up-to-date, you won't see that pop-up either. uBlock handles it just fine. During early days of YT trying to force me to disable it, all I had to do is to open the settings, update filters and it was just fine. Thankfully it's been peaceful now for long time.

This isn't correct. A few weeks ago it started stopping me in FF with uBO running.
