I won’t argue that the eshop isn’t full of shovelware because it is - but even shovelware needs to be preserved.
The problem with this line of debate is that there are some games worth having that are only on the eshop and it’s still a digital barrier to you truly owning the software. Saying most games are available on a physical medium doesn’t help those that aren’t and it’s a situation that’s only going to get worse.
Essentially what I am saying is that none of the big 3 are innocent here and just because some are slightly better than others doesn’t make it okay.
