The tag means that you will continue to develop it. The second you decide you are not developing it, the early access tag is a lie.
That said, the idea that it's OK to abandon a game you sold people to make another one is also disgusting and also makes you a piece of shit of a person. The disclaimer is not a free pass to be a trashbag. It does not excuse or justify throwing away customers. It is merely an acknowledgment that you might fail.
Frankly, not only should you be required to remove a game from early access before you're permitted to launch another, but that release should be validated by Valve, and sent back with a "nope, this isn't a product" to get to release. Until it's actually a full featured game, you shouldn't be allowed to do anything else. If your studio fails under those conditions, it deserves to fail. A studio "rescued" by shitting on customers to fleece new ones is a trash studio.
