I use Sync and don’t pay anything. It’s brilliant and the ads are basically invisible and rare.
Literally was the best Reddit app and it is a fantastic port to Lemmy.
You can choose to pay the dev if you want to. I haven’t yet, but likely will if I spend more time here.
The older and shittier the ISP the more blocks of IPV4 addresses they have. They have blocks from when they were given out willy nilly.
New ISPs, the ones that compete and bring the prices down have to buy addresses and that costs money and is a cost bigger and older ISPs do not have.
This is a case for regulation - either mandating a move to V6 or mandating the release of stockpiled v4 addresses. ISPs will not do that on their own, the addresses can currently be sold for lots of money.
