I’m personally huge into scratchbuilding and kitbashing (so much so that my own blog is named for it) so I understand the love for it.

I don’t see a problem with high quality out of the box kits. Some people want to just paint, and at the very least it gives scratch builders some reference material to draw from.

Any particular attitude about excluding scratch builds or conversions from play, and only allowing official models is a different matter and I’m 100% against that. But somebody just owning and showing off their cool and well painted minis just somebody hobbying.
