Is there any need to trust Tor exit nodes at all?
At least VPN providers need your money and their reputation and you can chain them for tor like privacy without the poor performance and anonymity.
(Tor exit nodes have been caught injecting malware into binaries downloaded over HTTP through them, for one possible problem if it isn't)
It's more accurate to say bad actors have been injecting malware into HTTP-downloaded binaries. Some of these bad actors use Tor exit nodes, some use free WiFi hotspots, and some run their own VPN services. Framing this as a Tor problem is like blaming violence on weapons instead of the perpetrators.
