As a former cal.com advocate, I am now going to be switching my two companies to cal.diy or a similar alternative and canceling my cal.com subscriptions.

I am now actively rooting for cal.com to go out of business now as a cautionary tale for any company thinking about taking open source projects proprietary.

FOSS || GTFO

You might want to double-check the cal.diy maintainer before your wish is granted..
