If you’re concerned about this coming from Meta, you haven’t been paying attention. This is not to excuse Metas responsibility in the enshittification of the internet, but as a hyperscalar they of course have been pushing computing technology for a long time, and many of it openly available. CRAM will probably be upstreamed into Linux and I assume is therefore already licensed under the GPL. Meta Research seems to be operating in a much more open and useful way than the rest of the company.
