Errr... no it's not. It's reassuring their customers that the service they pay for will continue to operate. As one of those customers, I'm glad to hear it.
I'm not sure if they do but how much does Compose actually contribute to the project? Will they contribute in the future?
Are they simply a parasite or will they invest in their business by improving the software they sell? If they won't then I would never use them for anything as they are providing a service for a product they have no control over and no desire to invest in and improve and I'm not interested in tying my business to that.
We improved most DBs we sold. In fact, I think Compose is valuable to most DB companies ... nothing like real world ops problems to learn about customers.
