Let's say you successfully create a drop-in equivalent to Salesforce that anyone can use for free, and sales teams decide they like you enough to do so (good luck). It takes off, and Salesforce goes completely under.
They can no longer afford to pay salaries in this hypothetical and everyone is let go. You have done the equivalent of laying off Salesforce's entire workforce. You've replaced a system that pays 15,000 engineer salaries with a system that pays no one and benefits other SaaS companies, no?
I really don't get it.
I suppose everybody is allowed to feel however they wish about such and it seems that this project is the culmination of some of these feelings.
on the other hand building this stuff would be a nice portfolio project for those laid-off people and it might help them find a new job :)
