i rather pay money and get a 1y or 2y certificate rather than use those ephemeral let's encrypt ones for free. The overhead of automatization(implementation, maintenance, support, patching, updating...) is not worth it.
This seems to have started around August 2020.
So instead they will sell "subscriptions" where you get a new certificate on expiry. So technically they will still sell you multiple years, but as a subscription.
