It it quite funny, elasticsearch is also kind of wrapping an open source library (Apache Lucene) and selling it as their own product.
Could Elastic's business model survive if lucene adopted the SSPL license that Elastic has, saying it's the "spirit" of open source?
That is an interesting question.
MySQL for example took a proprietary API (the mSQL API) and implemented an open software for it. Then Oracle bought MySQL. MariaDB started and it quickly dropped full compatibility. Options for the developers/users. Great.
AWS/GCP/Azure on the other hand distorts the market. Just as Google/Apple/MS fund Chrome/Safari/Edge development from other sources, thereby distorting the market, forcing browsers to be free as in beer. (Which arguably hurts the market.)
You are suggesting this is not correct?
