If he doesn't want to deal with customers, maybe he shouldn't be selling this as a product
That said, there's nothing wrong with discontinuing the product if he doesn't feel like working on it any more
The advertisement is for the iVRy Driver that he developed for some other hardware options.
The work he's done on reversing the PSVR2 is unreleased and closed source for now.
That's not what they are selling, 'this thing' is work on the PSVR2 not PSVR, one of the things supported by his existing, available now product.
1) Only ever use it from a desktop browser with a sufficiently configured ad blocker. The mobile apps are intentionally designed to pull you out of the thread with only a single line of text delineating where it does so and no way to actually continue with the thread. It's a miserable experience and the people responsible should be ashamed of themselves. They try to pull the same bullshit on the website but it's more obvious there.
2) Twitter has two reply modes. Direct replies are put under the post they're replying to, much like normal linear forum discussions. But then there's retweets. They create a new thread, quoting the previous thread in the topic starter, so to speak... and unlike the standard linear model, the topic starter is done by top posting, with the quoted bit below.
