Corruption is a sufficient word for this. Quality isn’t determined by a popularity vote, so foregoing quality in order to appeal to popularity with all it’s financial benefits can be called ‘selling out’ which is a form of corruption.
Media are full with this, going both ways, artists, musicians, directors who go after the sweet smell of cash and take the edges of their products, or those who plunge back into depth and accept the obscurity that so often comes with integrity.
True, true. Another aspect of games where vocabulary falls short as far as I know.
