It has resulted in at least one new monthly contributor and hope others do the same.
I wonder if the decline in donations has anything to do with Prusa refusing to properly support Octoprint in favor of their own half baked, awful competitors that are no doubt in furtherance of their quest for SaaS rent seeking (BambuLabs fear? jealousy?).
The MK4 and XL are barely functional with Octoprint and Prusa has indicated they intend to keep them this way, as they did with the Mini. That's a large and growing market now not really supported by Octoprint.
They instead want you to use Prusa Connect, their currently free farm management software that requires internet access and all of your data to manage your local network of machines. No doubt this goes non-free the second any momentum is achieved.
I say 'want you to use' because their local network solution, PrusaLink, is a barely maintained skeleton of a project that replicates a tiny portion of Octoprint's functionality, poorly (4kb/s uploads! 27 char file name limits!), while missing many critical features, has no plugin support and many many bugs. No doubt the prioritization within Prusa is Cloud and not the local functionality you actually need and your machines are capable of.
By reducing Octoprint functionality to the level of their own rudimentary offerings on their newest flagship printers they certainly make the case for using Octoprint far less compelling and paying for it even less so.
Octofarm shutting down also probably didn't help things either.
