If you're not going to do the work to figure out what the corruption is, at least include the two PDFs so other people can look at them and see what happened.
I'm sorry, but last time I checked neither Apple nor ABBYY pay my salary. I really don't understand these takes. If Apple or ABBYY want my PDFs, they should be able to find my email address rather easily. Your tl;dr version of the post is completely unfair. I publicly criticize Apple because they are breaking something that potentially affects a lot of people who are unlikely to even know about it, and they are doing it for at least the second time now. If you don't think that's worthy of criticism, I don't know what is.
I also love how so many people assume I didn't already talk to support and file radars. I guess you had better luck in the past than me, but I can assure you, these options aren't always as useful as you might think they are.
This is a fair bar for conversation, in person or online. One can be more demanding of a public write-up.
