I don't really know myself either, to be honest. I totally agree with what you're saying, it makes perfect sense. I just honestly get way too worked up about these kinds of things sometimes, and end up forgetting what point I'm even trying to make, lol. I should save that energy for the Moenovels and SakuraGames of the world, heh.
There are some issues with the store, but it just launched so I am sure these are issues they will address in the future. (Like being unable to sell one of their own games. I am interested in seeing how they go about handling this one.)
I do think they should still offer a link to their patches on the store, or if this gets them in trouble with their payment processor, at least mention that the games have been altered and that there is a patch available to restore the content. New customers finding this store, perhaps through the manga and light novels, won't know what "this is the all-ages version" means. The idea of patches being needed to play the full game is probably alien to them. They will probably get more "mainstream" customers specifically because Sol Press is a more "mainstream" company. I suppose this is the only real gripe I have with the site. The other companies you mentioned do this. KaguraGames offer the patches on their own website, which is linked on their Steam profile, and while CherryKiss does not have a store, we sell our games totally uncut on Steam. The theme here being that the patch / uncut versions of games are easily available and not hidden away on a secondary site that you need to know about to find. That I guess is the only real thing I would like to see them fix.
