Not the first time for me that Twitter f*cks up badly. [0]

It's not your account. It was never yours. It's Twitter's, and they can do whaterver their TOS allows them to do with it (and they can change their TOS in whatever forms they want... so effectively, they can do whatever the hell they want with any account, as long as it's not illegal).
I have created perhaps a couple of accounts on Twitter in the last decade. Always treated them as ephemeral stuff (same for any other digital thing I don't pay for... and even for the ones I pay, I'm very suspicious about them. See Netflix introducing ads for paying customers. What a joke).
Twitter is a dumpster fire.
They know it is not 'your' account anyway. Given how they are going down the path of a tech dystopia, its probably for the best that your account was permanently suspended as they can choose who to give a platform to or do business with.
Now that they have de-plaformed you, they have made it much easier for you to stop using their service as this can happen to anyone.
So you should "Be nice" and once you have been de-platformed, you should still be very happy that they did.
