But I don't think this developers of Bitcoin are doing anything to douse this problem of high transaction fee because it has passed one month when the hike of fee started but nothing has been done to stop this problem
This has been discussed on the mailing list since as far back as January last year, when the first wave of ordinal spam hit the network. And it was rightly pointed out on the mailing list that banning this kind of data is technically impossible, as I've also said many times in this thread, since the spammers can just move their data to other parts of the transaction which are impossible to ban, such as embedding it with public keys themselves.
People have been waiting for this transaction fee to come down so they can withdraw their money
Have you considered your biggest issue is using centralized exchanges from which you have to withdraw "your" money in the first place? Why should we start censoring transactions and adversely affect the future security of the network because you didn't use bitcoin peer to peer but instead let a third party take ownership of your money and dictate fees to you?
Why were altcoins invented?
For 99.99% of altcoins, to make their creators rich.
