I've seen TV commercials lately for a commercial VPN that sounds very attractive.  But, although it's advertised as available for Linux (among others), I'm not sure it would be easy to configure for a specific Linux system.  I think one that's provided by our own repositories stands a better chance of working out-of-the-box for my KDE Plasma systems.
  
So I'm seeking recommendations from those of you who are using Plasma, and have good experiences with a VPN that's available on Solus.  One thing that I'm concerned about is that when I experimented with a VPN years ago, I was so anonymous that I couldn't order anything from stores I'd patronized for years.  They didn't know who was, placing an order from Bangladesh, or wherever.  And likewise, I couldn't send a message to my doctor, or access a streaming service I paid for.  And paying for anything with a credit card was out of the question.
Is this still an issue?  Or is the technology more advanced by now?  Most of the time I spend online is with people and places that need to know who is contacting them.  I almost always need to be able to log on with my credentials.  Any recommendations will be appreciated.
