Has Elastic just allowed their comunity to ignore their SSO tax on self hosted instances?

Because its [split licensed](https://github.com/elastic/kibana/blob/main/LICENSE.txt), depending on individual source file. Which means they put in the effort. For example your linked file is ONLY licensed under ELv2, so no you cannot do that. Looks like they were very careful at selecting what you can and cannot modify. What Elastic is doing is of no surprise to anyone. A few years ago they realized that service providers were making more money on their product than they were. Specifically Amazon because they provided a nice and easy way to build your own environment. Amazon also saw it fit to build their own version of the licensed features with different collaborations. This is how open source works... You can do that. Elastic didn't like that so they fully relicensed. When they relicensed... Amazon already had a team specializing in the build, so they just forked from the last open source version and have built a whole lot of features. Because Amazon makes money from the hosting, they can continue to take advantage of the opensource community. Since then, an enormous amount of platforms have moved AWAY from Elastic and onto Amazons OpenSearch, such as GrayLog, Wazuh etc. OpenSearch has continued to evolve and grow with new and modern features that people have been begging for Elastic to implement for years. So this is Elastics weird way of begging for the community to come back, since they've now lost customers that were paying for Elastic because their platform required it. What's interesting is they're still trying to paint themselves as a hero instead of just saying "We done goofed".
