PayJoin is a privacy improvement for bitcoin. Payjoin solves the sole privacy problem left open in the Bitcoin whitepaper, that transactions with multiple inputs "necessarily reveal that their inputs were owned by the same owner," because both the sender and receiver of a transfer contribute inputs to the transaction.
Transaction surveillance companies heavily depend on the common input ownership assumption which is broken by PayJoin transactions. So if those transactions became even a little bit widespread they could massively decrease the reliability of blockchain surveillance. Those who adopt PayJoin would find their privacy improved from strangers analyzing the blockchain. For example a surveillance company spy would find it much harder to figure out which addresses and transactions belonged to a particular merchant that was using PayJoin, or who else transacted to them.
PayJoin transactions can be made indistinguishable from regular bitcoin transactions by design, so it's very hard to get an accurate number for how common they are.
The most widely adopted PayJoin protocol standard is BIP 0078.
