Just to be clear here. It's bait-and-switch because they sold you a subscription product 2 years ago, and they are now changing the terms of the product (and presumably are not going to penalize you for discontinuing your subscription)?
Do you feel that they are obligated to never change the terms or discontinue certain policies once implemented for the lifetime of the company? What company would ever want to operate in such an environment where they had to make all decisions up-front and those decisions were set in stone until the end of time? Is the price also set in stone until the end of time?
Most PIA users pay yearly, so it's completely understandable to feel ripped off I think. However, this is really just a matter of a few big providers implementing stricter geofiltering, blocking datacenter IPs, etc. Nothing PIA could do about it though, it's a risk you take if you understand how these things work.
Many of these same providers have just blocked VPN IPs and you can still use a cheap VPS to circumvent though. Some nice docker openvpn containers around...
