From what I saw on other forums and Youtube comments, alot of people are ditching Unity amidst this pay-per-install controversy. People are searching for open-source alternative and there are alot of relatively unknown engines mentioned, however, in none of those comments I saw someone mentioning Defold. Mostly, only Godot as direct Defold competitor is mentioned.
This is great time for developers learning about and switching to Defold with a little viral marketing.
