quite the ramble, not sure why you needed to create a brand new account to say it though. Inatari sets the public release time, from his perspective the game leaking before that will be detrimental to him and his income, which is something only he will know the specifics of. perhaps he will change it one day, or perhaps not.
Im also not sure about your last point either, the 4.8 changelog post had more likes than any post he's made (on patreon at least), and the average number of likes the posts get has increased a ton the past few updates, meaning the games popularity is really increasing, even with the free release taking a month.
if people are interested enough they'll buy into it, if not there's plenty more to do in life as you wait for your turn when its out for free ¯\_(ツ)_/¯
