To me it reads like an ego trip rather than any kind of righteous vendetta against the author. Implicit in "look at the dumb thing this other person did" is "I'm smarter than them because I noticed the dumb thing".
1) Protecting the installer will take care of most casual piracy
2) Protecting the VST might lead to unpredictable performance and issues on something that needs to run in real-time
So they chose to only protect the installer, which seems like a very user-friendly choice. I both enjoyed the writeup and want to second supporting the developer by buying a license.
It’s kind of a rote “this is a bad implementation” post that’s pretty obviously about the DRM vendor and not the guy that made a bass boost plugin for djs or whatever it is.
