Probably falls under same case law with Sony’s VCRs being able to record cable TV way back when https://en.wikipedia.org/wiki/Sony_Corp._of_America_v._Universal_City_Studios,_Inc. Though this predates use of internet for streaming/piracy/etc, supresupreme court could interpret differently now

OpenDesk seems more aimed at municipalities and larger orgs, whereas cryptpad is better for smaller orgs - the 1000 user “large” edition may be too small for ICC. I’m assuming they aren’t selfhosting the community edition of open desk and wanted the support.

Or maybe open desk just gave them a better deal. Who knows
