> rather than just tearing others’ work down as I’m currently doing.

Your criticism looks authentic, based on real study and expertise. I think it is a valuable gift. It is only when such a thing become compulsive that it can fairly be called "tearing down."

Looking at your issues, you are calling out real flaws and even provide repro tests. If I were a maintainer who cared, and not just running a slop-for-stars scheme, I'd be very grateful for the reports.
