Here’s what Sony said at the time:
Recently, we notified players that PlayStation Store for PS3 and PS Vita devices was planned to end this summer.
Upon further reflection, however, it’s clear that we made the wrong decision here. So today I’m happy to say that we will be keeping the PlayStation Store operational for PS3 and PS Vita devices. PSP commerce functionality will retire on July 2, 2021 as planned.
When we initially came to the decision to end purchasing support for PS3 and PS Vita, it was born out of a number of factors, including commerce support challenges for older devices and the ability for us to focus more of our resources on newer devices where a majority of our gamers are playing on. We see now that many of you are incredibly passionate about being able to continue purchasing classic games on PS3 and PS Vita for the foreseeable future, so I’m glad we were able to find a solution to continue operations.
I’m glad that we can keep this piece of our history alive for gamers to enjoy, while we continue to create cutting-edge new game worlds for PS4, PS5, and the next generation of VR.
Thank you for sharing your feedback with us – we’re always listening and appreciate the support from our PlayStation community.
However, it seems that while the store will remain open Sony are sticking to their guns when it comes to publishing new games and there will be no new Vita games available on the store after this summer.
Sad news – it seems that the old deadlines for new digital releases on PSVita are still valid. That is, the store will continue to work for customers, but the games will stop coming out this summer😞 #VitaIsland #Vita2021

If you now re-read Sony’s statement you will see it only ever mentions keeping the store open for purchasing ‘classic games’, not new ones.
