I view FB as a negative force in the world but mostly not malicious.
Although FB software doesn’t “force” any connection, as the comment above so well illustrates, there can be incredible social pressure enabled by FB to do something such as stay connected to an abuser.
If you consider FB to be literally the software only, rather than the software plus community, then you may be technically correct. This IMO is a narrow and limited view of what companies and products are.
It’s definitely worth it. In many states you can do it online for less than $100.
If you wrote a bug that cost one of your clients to loose a sale you could be personally liable for the full amount.
Just spend an hour doing it and don’t risk losing all of your savings. You don’t want to go to court with a company that has many more resources for lawyer than you.
This is a no brainer. Advice saying not to do it is just plain wrong.
It’s ridiculously easy, you pay your taxes almost identically to how you currently do if you make an LLC and are sole owner.
—edit I see you are not in US. My advice is more specific to US.
