very likely it is not crypto related since the number is a way too big compared to our community
Yes, i have also been using Libreoffice for years, but this is a fundamental problem with all "subscription based" services, they are centralized. I think the next scandals might come from streaming services. Gaming networks have already been compromised (ie. Sony's). And is the very reason KYC is so dangerous. Data identity theft is only increasing and the more we are forced to trust our credentials to third parties, the more we give to those who steal it.
This is the fundamental problem with government "controls", the almighty police state is also the very source of the problem. And so are the corporations that do the same "in the name of security", end causing the opposite.
Years ago i couldn't believe people actually accepted the idea of "software subscription", and here we are, looking how this mess unfolds.
Worst thing is, this won't the last one.
