40% actually seems reasonable for a flip into maintenance mode. That’s what PE firms do when then buy cash cow businesses. Dramatically cut engineering on new functionality, cut back on sales and marketing, remove all redundancy in operations.
Anyone who has counted on a vendor that went private or was bought by a rollup firm has felt this pain.
Better to do it all at once than repeated declines.
I first entered the workforce at IBM and several months later they did layoffs (resource action). Every six months after that for my 6ish year tenure there were more resource actions.
To this day I walk into the office each morning thinking today may be the day I get laid off. My wife doesn't think it's a healthy mentality, but I'm not sure I know another path of life.
This is to say at least it's done in one fell swoop. Repeated layoffs are certainly demoralizing.
