This happened before back in 2014[1] and also involved Twitter blocking access to certain posts or accounts under the threat of a total block. What exactly are their alternatives?

I suppose they could drag their feet a day or two until after the election, but after that, they'd be subject to fines, complete blocks of the site (like what happened to Wikipedia[2] for almost three years), and who knows what else. They could attempt to fight this in Turkish courts, but that might be futile.
