The tech companies you identified are getting hit 1st. I expect to eventually see fallout in Fintech, Realestate, Advertising, anyone selling B2B SaaS (particularly to marketing/HR/ sales departments, SMB), etc. It will take time to feel the 2nd and 3rd order impacts. Hopefully, we bounce back quickly, but it's hard to not be a little concerned.
Unless their investors believe in a V-shaped recovery afterwards, and are willing to spend money now to gain market space from competitors who would die in the meantime.
