Not the poster, but Microsoft Powerapps had a massive price jump a few years ago, followed by a pretty large decrease last year.
Through the grapevine I have heard the same about Mendix and Outsystems - in my company we found that hiring internal developers is cheaper than paying the licenses at scale. (About a 10k employee company)
It may work for smaller depts and apps, but Retool or Airtable is often sufficient for these teams, and much easier for non-developers to learn. We do use Appian and Pegasus for some smaller depts.
