The fact that someone makes money spying on me doesn't make it illegal for me to take countermeasures.

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.

This is a weak argument because YouTube isn't a public street it's a private business

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

And YouTube as a private business can refuse to serve people using ad blockers or alternative clients. But that doesn't make it illegal to use an ad blocker as the parent post was implying.
