I've seen this be a hit and miss. My previous product manager has a technical background and moved into production management because he thought product managers suck, and wanted to be a force for good. He was one of the best product managers I worked with.

However, the very unfortunate truth is that _most_ engineers end up in product because they weren't good engineers. So they don't have a good internalised engineering culture as product managers either. My current one is by no means a horrendous one, but is definitely closer towards the bad end of the spectrum, and they moved to product out of management. I'm giving them the benefit of the doubt for now, because they've just started the new job recently and maybe it's just friction from learning on the job.
