Sounds like you need balance, my friend. If you have a job that is brain draining, best not to spend lots of time on a hobby that uses loads of extra brain power. Perhaps try spending time doing something physical or meditating instead of adding more mental stress to your day. When your time frees up in the future, you'll be easily able to pick up where you left off with coding.
I believe "music that incites violence, hatred or racism." Is defined as: any music that makes a lot of people upset on any given day, esp. when it is trending on Facebook or Twitter.
While I don't agree with your first statement, I do agree with your second.
If a company controls so much of the internet that they are able to silence an entire group of people, that's probably not a good thing. Where they draw the line today may be different from where they draw the line in a decade. Once the line is drawn what does that mean for other content that Google doesn't agree with?
Companies like Google and Facebook control access to so much content that, with the tweak of an algorithm, they could make it appear that there is no one else in the world that shares a controversial viewpoint that you might have.
That being said, Google is a private company and should be free to block whatever they want. If enough people don't agree with them, over the course of time, other competitors will rise.
