Does anyone at Apple do quality control anymore?

Big Sur Beta 5 won't install for me or many others it seems. I'm on a 2017 iMac 5k. The iOS 14 betas have been absolutely terrible and my 3rd gen Apple Watch claims I have to delete files in order to install the latest beta on that. I have 0 songs, 15 phantom photos (no idea how to get rid of those) and just 6 apps. The update needs 2.9GB of space and despite having nothing on the watch really I only have 2.7GB free. There is no way for me to even clear some more space.
I wouldn't mind or complain if I wasn't paying apple $99 to be a developer. Not to mention the thousands of $$ paid for the hardware. The very minimum we deserve is these betas are actually able to be installed.
