Extinguish basically now means:
'We fork the best open-source tools and they sit on our cloud and are more secure and scale better than if you self-hosted it, and is completely free to use.'
Paid competitors can't compete or will struggle to compete with free, given that it is open-source and more secure and is sitting on the cloud and scales. Lastly, nobody got fired for buying products with Microsoft® stamps.
