Oh, of course, I fully agree that the instrument itself is not a problem. My problem is not with having a “lite” version of an instrument, but rather with having an instrument as an ADVERTISEMENT. This is essentially a “check out my website!” plug, and that feels very… not PB. To me, this is a place where people create and share, not advertise commercial products.
If later, someone wants to MAKE a commercial product from a PB library, that’s awesome! SA Labs Arctic Swells is a perfect example of this, as well as the Labs Pipe Organ, the Cinematic Soft Piano, etc. I have no problem with that. My problem is with stripping down a library, and posting it on PB as an advertisement for the full version.
I could see it leading to lots of companies doing plugs and “lite” instruments, and turning PB into an advertisement for others websites.
