You can take pride in the fact that other servers have borrowed ideas from yours. Many servers have adopted elements from mine, and I find that gratifying rather than frustrating, knowing that I was the first.
Many servers, including some prominent ones today - they know who they are, have consistently followed this practice. They assert that they are not pay-to-win, but in reality, they engage external markets to sell items on their behalf, ultimately generating revenue.
This has always happened, and I don't see anything new.
Years ago, there were servers that were much greedier. They would sell in-game items and even partial GM privileges to their biggest donors for the right price. So, I don't believe our current era is the worst.
This game has been around for a while, and the primary reason it's still being played is due to private servers.
