Until about 2014-2015, many large companies wouldn't have looked twice at Elasticsearch. The companies you list using Solr have been invested in search for 10 years or longer (predating Elasticsearch), and may have high switching costs.

For sure they would have high switching costs. They would be switching from an open-source (and free product) to which they contributed changes to a commercial product. License alone would be a serious discussion point. So, that's a fact.

Was there an opinion in there as well that you tried to convey?
