I had checked as soon as I found out about the news the other day and it was there. I just checked on wayback machine and you're right, it was removed for some time. However, if they're willing to put back that claim immediately, I doubt that their intention was to drop the free plan anytime soon, but probably it was to incentivize people to use the paid plans. Enshittification must happen sooner or later afterall, but fortunately vaultwarden exists and the export feature is highly unlikely gonna be removed immediately as the free plan disappears, so people could just switch to a third-party or self-hosted backend as soon as that happens.
