In addition to all this, I’m also of the opinion that most users just have software “lumped on them” and have little to no recourse for complaint, so they’re just forced/trained to put-up-and-shut-up about it.

As a result, performance (and a few other things) functionally never gets “requested”. Throw in the fact that for many mid-to-large orgs, software is not bought by the people who are forced to use it and you have the perfect storm for never hearing about performance complaints.

This in turn, justifies never prioritising performance.
