There have always been people that get around laws of not being able to charge for something by charging you for something else and giving you whatever it is for free. Or they don't charge people to be part of a special co-op that allows them access to all of their data. Or access to a shared system that has the data on it. However that doesn't mean that they don't charge companies for a flash drive that just so happen to contain your information on it. Its good to keep Mozilla on the level with expectations, but frankly changing browser platforms isn't going to help - even with full Telemetry on, Firefox sends less info, in a more transparent way, to an entity less likely to abuse it, than just about anyone else. or other open-source variants of Firefox instead? That's fine, but realize that if Mozilla and Firefox itself suffer, so too will all of these other programs based upon it. Do you like customized IceWeasel / WaterFox / PaleMoon etc. Mozilla and Firefox aren't perfect, but if you want to talk privacy, ethics, openness/standards, and other geek-centric stuff, they're one of the best around by far. However, being upset about this when nearly every other major browser, especially Chrome and those based upon it, has something worse and opaque (as well as being generally controlling, developed by a for-profit advertising company, foisting proprietary services etc ), is not realistic.

Do I think it should be opt-in in all cases? Of course.

Mozilla has some of the most transparent Telemetry data and in many cases, it is in fact opt-in depending on the version you use. We should absolutely advocate for this sort of thing to be opt-in, but frankly this isn't some new scary thing - is a part of Mozilla's telemetry for Firefox and can easily be turned off.
