If you think from a scummy gacha company perspective it all makes sense.
They develop the mode silently only giving vague information that can really mean anything "multiplayer" "harem" "DLC"
- that allows them to keep getting support from people that would long quit, to this date people give them money without knowing the pitfalls that await because that information is nowhere to be found on patreon page.
They withhold new content for months - artists have nothing to do with developing online mode they kept working on animations but none of that was released for patrons - as result they have new animations that people need to engage in the new system to unlock.
The is reason why you can't have private lobby or why likes exist. They want you to see other people that means potentially see people with outfits/animations/characters you don't have and spark that desire to have those things. Easiest way for that will be going to shop and spending those $$$.
Trim your expectations.
If the content is streamed it will require accounts that have that new content unlocked in order to sniff it up. That is quite a bit of work. While eventually it will happen it may just not be worth the work at this time as the game is buggy as fu-k on it's own. Also they need to keep adding new content given the nature of business they are running now.
