Your engineering focus is exactly the problem! Salesforce as software is a piece of crap, no one is arguing that. But companies continue to buy it because (a) it's familiar to all their sales & marketing people, (b) SFDC is all set up to be able to sell into other large companies (not a trivial task), (c) it already does all the legal, regulatory and compliance stuff, worldwide, which is hugely complex and boring to replicate and needs people on the ground in multiple countries to achieve. Coding is not the problem here.

Many here don’t really get what a software firm is, do they?

These people are deluded and have never operated a business enterprise themselves.
