This isn’t a small number of customers, but the fact that you choose to interpret it this way is telling.
Steam early access of for software that is in Alpha or Beta. Let’s review the software development lifecycle definitions.
Alpha
excerpt
“The alpha phase usually ends with a feature freeze, indicating that no more features will be added to the software.”
Beta
excerpt
“A Beta phase generally begins when the software is feature complete but likely to contain a number of known or unknown bugs.”
These are clear industry standard definitions, not some misunderstanding from your customers. You guys aren’t the only ones who work in technology and while wordplay might sound good to some who don’t know any better, some of us do know better. Labeling it as early access is appropriate until it is feature complete. Posting an incomplete module to your store page as a completed one is dishonest and is everything wrong with the software industry. If you hold this community in such high regard and you claim then do the right thing and keep the label on as long as it should have it.
