Donald Trump to launch social media platform called Truth Social

I'm interested in whether the technologists employed by this company will be able to pull it off. I'm by no means an expert, but my understanding is that in order to support a large scale social network, with typical social network features, the implementer needs to have some pretty robust solutions for a large breadth of different problems/design considerations.

On the one hand, a lot of the technology used (in what I imagine a typical high level social network design would be) is readily available and well understood by actors in the job market (I think?). On the other, assuming there is a wide audience who would be interested in immediately using this product, I wonder if they'll be able to pull it off without being plagued by D(D)oS attacks, targeted hacks, etc etc.

Note: To be clear I'm just riffing on the technical challenges of this undertaking (making a new social network) and not trying to get into a political/ideological argument.
