Flexibility. As I said some post higher up, this offer has clearly nothing to do with Covid-19, it's simply a FX-workstation-as-a-service offer, and its selling points are the same as for all DaaS offers, but aimed to an industry which is especially changing and unpredictable: FX companies can double in size while working for a big contract (some blockbuster movie), and they never know beforehand what they'll need, as the director can (and will) change his/her mind at any time.
