If the money were to be used to secure the network somehow, it would make sense.
If the money just goes to the creators... it was all just a money grab.
However most of the potential token supply (like 50%) was premined/airdropped to ssh keys of Github users with >15 followers.
That's not necessarily fine if the fee is in custom tokens. By burning they are just reducing supply, locking in the amount paid and increasing the value of their huge holding. It's pretty terrible.
Ofc in this case the Devs and the "sponsers" have 10% of it, so yea.
