Microsoft doesn't release developer builds to the general public, and rightly so, as demonstrated within these forums.
The release of a future Operating System beta, is not for the general public, it is for developers, who have an interest in ensuring, their work is compatible to the system, and as they have an understanding of coding, and IT architecture, are best placed to help Apple in ironing out issues.
The whinging, moaning, and sense of entitlement, demonstrated by many with this thread, and many others, demonstrates why developer betas, should be for them.
Apple is not releasing bad updates, they are releasing beta software. Let me say that again, beta software, defined as 'a trial of machinery, software or other products in the final stages of development, carried out by a party unconnected with the development process.'
And yes, I do expect the world, and I, to just wait. No first version is the same as the released version, and what most are complaining about, is simply their visual viewpoint, because the no little about coding and IT architecture and design.
Update: I have had a response from an email sent to Tim Cook, and there is agreement, that 'developer betas' being allowed to be utilised by 'public', outside of the 'public beta', program, needs addressing.
