I used to work in the ink cartridge industry. This is not new. HP has been actively blocking non-HP cartridges for at least 10y.

The issue is that there is a cat and mouse game between an handful HP "alternative cartridges" manufacturers and HP. HP is actively trying to detect and block non-HP cartridges while the manufacturers find a way to bypass it.

What probably has happened here is that HP had pushed a SW upgrade that detects non-HP cartridges a bit better. The manufacturers probably already found a way to bypass it and new cartridges will work on this firmware.

Reading the headline I was half jokingly wondering if they did those lockdown updates like a one-off project each time or if they already have a routine schedule, like a key change mid-March every second year.
