I am running a program called Insiders' Updates - which emails sponsors each week and gives them access to a portal, to get recurring revenue and offer more value.

The "Treasure Trove Portal" has discounts, and updates since 2019 now, as a user of openfaas or any of my software, there's definitely value here that shouldn't be passed up.
The weekly features are not about my OSS projects, but about the industry, marketing, business and Open Source - so that there's something for everyone.
The comment about companies not using open source is not really valid, them not valuing the time of maintainers would be more accurate.
