In many countries, a VPN provider can be significantly more trustworthy than an ISP. In Germany, for example, you can have your home searched simply for insulting a politician. The ISP will then immediately hand over the data to the authorities, which most VPN providers do not do. The same goes for torrents. If some random law firm sends a letter to Telekom saying, “Hey, your customer downloaded a movie please give us his data,” they’ll do it right away. Mullvad, ProtonVPN, or even dubious VPN providers like NordVPN don’t do that.
