I doubt it. The ongoing operational costs of a mega constellation like this is huge and I doubt they will be able to sell their services to maritime, aviation and military sectors at a much higher price than existing operators.
They will also meet hefty competition the next few years from Amazon Kuiper, Oneweb and I assume existing operators are scrambling to meet the competition. Interesting times.
They already sell it to maritime and aviation sectors at significantly less than existing operators, though significantly more than the regular service.
But at this point in their plan it doesn't matter if they undercut existing providers. If the marginal cost of the extra client is small enough then it is just extra revenue. And you get the clients operations dependant on that extra bandwidth that they won't want to give up.
