Excuse me, but does the author demand that the author requires exclusively for altruistic purposes or for profit?
And you read the hat more carefully. where is even a word that this is generally the author's idea? This vote has been initiated by users. I want it to be clearly understood!
for the sake of, as you say "profit", it was possible to sell 2.x for otd money. so no, just buy once now.
but in general, this is called earning and there is nothing shameful about it, nor can it be, especially with such quality. As for me, the author has really sold off, there are no full-fledged alternatives to this player.
