I've read your comment a few times but cannot grasp the intended meaning fully. the creator claims to have made this change clear in multiple locations and on multiple occasions, accusations of sabotage therefore seem like rephrasings of 'i didnt read anything while upgrading my copy of this library'
'user data' in this case refers to your copy of his software. how should software react when its explicit prerequisites are not followed? should software do nothing and allow incorrect usage, therefore potentially leading to unaccounted issues down the track? do we complain that adobe is petulant for restricting product access when license conditions aren't met?
when users don't follow adobes conditions for software access, adobe erases access to its software, which is functionally equivalent to an open source library deleting itself. however my argument here is very much diminished by there being nothing in the license.
