Steam was established as a platform that promised developers automatic and easy updating. Only option is run Steam in Offline Mode to stop an update, or if the developer offers a beta branch of older versions as the install option.

Yes, but should give me the option to choose, I am the customer , not the developer . Some updates are bad and ruin games , why not to be able to choose if i want them ?'
And this is a moral situation since the customer paid for a specific product as it stands at the time of purchase. If the devs want to alter the game , then or they have to refund back the money or give the choice to the customer to update or not .

Ask the developer to provide the version you want in the beta branch.

Some devs do , some not.

Exactly, ask them to if they do not.
