I've already posted the news to HN yesterday, but it didn't get any traction. Anyway one of the best remote collaboration platforms Bitrix24 is now free to an unlimited number of users until COVID-19 threat is over - https://www.bitrix24.com/about/blogs/bitrix24-tips-and-updat...
Bitrix24 is surely not "one of the best remote collaboration platforms". Had to use that service some time ago in a job and it was a convoluted experience.
