Sounds about right. I worked at an Alamo as a projectionist (wouldn't recommend it btw) and Sony was a pain to work with. We had a projector that forgot everything on its drives every time it got restarted (the files were still taking up space, but couldn't be deleted because it didn't know they existed somehow), and would randomly corrupt DCPs when loading or deleting DCPs on it. They had their engineers "looking into it" but I don't think they actually gave a fuck.
After something like 6 months they finally shrugged and send us a new SSD and did a clean install of the media server's OS and boom, suddenly it worked just fine. In the meantime we had over 6 months of having to play "find the corrupted DCP" and hope we didn't miss anything because if we did then that meant at least one show that'd be delayed or cancelled.
Edit: oh yeah and the projectors and software required to interface with them were loaded with all kinds of drm. If it had a Sony logo or talked to their software, it had its own drm. It absolutely wouldn't surprise me if Sony fucked a bunch of Alamos because they just didn't give a shit.
