YouTube makes money by spying on you and serving you ads
So yeah it's theft
So yeah it's theft
If your business is taking pictures of people on the street and I decide to wear a baseball cap and sunglasses, you're just out of luck.
You aren't forced to use it, it is a choice
And this application (FreeTube) is for the sole purpose of circumventing their (YouTube) monetization for the sake of convenience
I don't have a dog in the fight and I'm certainly not a fan of YouTube or Google, but you can't argue it's somehow ok just because you dislike ads or lack of privacy on a "free" video streaming website
I'd say both of those things makes it ok to do whatever you can to avoid them - given that YouTube appears happy enough to serve ads for various obvious scams that wouldn't make it past television advertising standards bodies.
