I also wasn’t aware of the survey at all and wonder how people even know about it.

The StackOverflow gave a notification. IIRC they sent out emails as well. It was shared on Lemmy too.

I don’t find the results that questionable at all. Feels like you have a strong niche bias. Which is fine, as long as you don’t assume you know better than a global survey on a popular industry platform.

There could be bias, but I don’t see it being that big. Microsoft is very popular in the enterprise field.
