5+ means more than 5, including 11.
You complain that devs use 3rd party hosters, I get it. Now go and complain that some devs only put demo version here and try to make you become patreon of their content... where you can download from their mega links ;-)
the excuse with the size limit is valid. Decreasing game size is not a priority if youcan host elsewhere and especially, if you offer the build on other sites as well, like patreon
