Fair points, but I think it's important to highlight the distinction between Elasticsearch BV, (the company - who will try to continue to offer commercial services and support to grow their business - fair enough) and the Elasticsearch project, which is the open source project.

As a company, Elasticsearch BV will reinvest back into the Elasticsearch project, which will increase the adoption and value of their commercial services. Both exist independently, but the success of either improves the other.
