PIA is not that new. They've been around a long time. PIA has been criticized by the security community for keeping "logs" but for general non-illegal uses it is probably fine. To add to the other comment about the FBI person saying use a VPN - for PIA that would be pointless for true anonymity because you use a credit card to sign up and instead of the ISP having all your browsing habits, if the VPN keeps logs - they have all your browsing data. Do you trust your ISP more or your VPN provider? That's the question you have to ask. Suffice to say I think it makes sense to rotate and use multiple VPN providers.
I use RingCentral and I have no problem using for example Surfshark VPN to access my RingCentral administration.
An alternative to VPN would be to use a third party solution like AnyDesk or another remote desktop option to simply access a computer remotely or virtual instance. I personally use an Unraid server at home that's plugged into business class fiber internet.
High quality VPN shouldn't slow you down at all. I am in Asia right now as we speak, working on ATX at home remotely through a VPN with no slow down.
For kicks I did a speed test. I'm getting 130 Mbps download and 15 Mbps Upload. This is more than sufficient for 99% of us.
For what it's worth, if I need to upload huge files - I'm not doing it through VPN anyway if the network I'm using is that insecure.
