I'm happy when anyone tapes. I'm happy when people make better tapes than I do at the shows I tape. Better tapes is always the goal.
It is possible to make great tapes with gear that isn't expensive? Of course.
What does expensive gear get you? Sometimes nothing, sometimes a better product. Some of these companies have been in business a very long time, so you get the assurance that you'll be able to get support down the road if you need it. That matters to some people.
Why did I buy DPA microphones? Because I like the form factor, available pre-amp options, off axis response, detail resolution, and general sound characteristics. Before DPA, I had schoeps. If DPA hadn't gone to modular cables and hadn't had microdot options, I probably would have gone schoeps Nbob again. Because to my ears, listening on my equipment, and for my use cases, they're the next best option.
If I had unlimited money, would I always pick the rigs I own? No, but I'd probably pick them most of the time. But sure, every scenario has a different potential solution.
All that said, no one should feel bad about using what they like, even the "zoomies". Make your recordings. Do what you like. Unless you're doing it for hire, it's all on you.
