Flickr and marketing 'blackmail'

Since 2018 Flickr has been owned by SmugMug. I received an email containing the above threat.  I consider this to be a kind of blackmail.  When I put my pictures up for free, there was no mention of these restrictions, nor was it some sort of trial.  When Google did a similar thing, they drew a line in the sand and told me I had to 'pay' for additional pictures - that's alright because it didn't involve me in any work to keep my photos.

I can download my pictures 500 at a time, so more than 36 downloads are required. I can only select then by day, so far as I can tell.  Each .zip that they create takes over 10 minutes, + 2–3 minutes to download. Then there is the processing effort once I have them all, and the difficulties of classifying loads of pictures from decades ago.  Then after that, a few hours of deduplication processing.  It's horrendous, and I'm given about a month to do it!
