As you know, domain extensions like .dev and .app are owned by Google. Last year, I bought the
http://forum.dev domain for one of our projects. When I tried to renew it this year, I was faced with a renewal price of $850 instead of the normal price of $12.
Since I looked at it in Turkish Lira, I thought at first that Google made a mistake when converting the currency, but it turns out that was not the case. Apparently, they are renewing generic domains like the one I own for $850 under the name Premium domain.
I could understand if I were to buy this domain from scratch, but I have been the owner of hundreds of domains for almost 20 years and I have never faced anything like this before. Once again, I realized that it is foolish to trust Google on any matter. Thank you, Google.
