No company is perfect but VMware treated employees like humans and valuable team members and listens to them. VMware did have its challenges but the pay and environment made it more than worth while to stay, and it's possibly the best company I've worked for. I wouldn't be looking at other options if not for the acquisition.
A lot of people are leaving not because of dissatisfaction with VMware but fear about Broadcom. Everything I've heard about Broadcom is bad, and it's not even for sure that you'll last long enough to be miserable working for them.
I know several people who don't have their green cards yet, so can't afford to wait around and see if they get axed or not.
