if you want you can chain traffic from a few companies through each other, so that no one server company has your info.
Please understand that there is no "perfect" security in the internet.
VPS are mostly for avoiding passive
surveillance, i.e. you can go to a site and it doesnt know your ip, and your isp doesnt know where you're going. This VERY GOOD, but of course doesnt help you if you're under active investigation because they can subpeona your connections, or if we assume that the whole of the internet is surveilled and effort is put into matching all inputs to outputs so as to maximize knowledge of everything. This is a goal of the US gov, but whether or not it's happening or possible at this moment, no one knows. If it is though, then Tor, I2p, etc. are all trivially breakable anyways because of traffic correlation, especially over time with fingerprinting.
I dont get the anti-vpn autists here, no one is saying they keep you safe if you do some thing very illegal and the government knows about it and wants to find out who. Literally people just wanna torrent stuff without their ISP freaking on them
