You’re probably referring to this [1]. I’ve checked all the runtimes and never found any actual malware. Started using it years ago when I was traveling internationally and needed to get around various region blocks and restrictions.
I was a subscriber as well. For about 6 months.
Even though it's incredibly cheap, I changed it due to a combination of all small defects like speed, 5 eyes location, engine problem and lack of double-hop. Although the last one would probably make the speed two times worse.
It also depends on how often you use it. If you say traveling, I guess it's not switched ON 24/7 , so the small things won't bother you as much.
However...
PIA has another problem. Test the setup file with VirusTotal and let me know what you will find :) Trust me, it's something you didn't want to know.
How long have you used it?
