You guys need to solve couple issues:
1. You still need to give a way to buy a lifetime license (meaning that it has bug fixes), but no support after i.e. 90 days. As in this case you give your customers a hope. And hope is important here. A hope is that if you will short on money, your business won't be ruined the same month. So that's why I'm saving money and I will buy 4 workers LiteSpeed Server license for 1299 USD (
https://www.litespeedtech.com/products/litespeed-web-server/lsws-pricing ), while as of now I'm paying 65 USD/mo. So this mean that it is pretty much 2 years payment. And it is investment for you to use the money. If that would be only allowing me to use SaaS plan, I'd never have bought it. But the believe that I can get 'owned' one, made me to make this decision. And it is really important ir Parler era, when Amazon AWS gave 1 days to move out. And any SaaS company can do that. So BE DIFFERENT TO AMAZON. And that will give you a customer from Amazon if you will buy correct ads.
Lifetime license here can also cost something like 1500 USD - just leave this as a hope, even if it is super expense, but as Elon Musk says - the only real marketing is when your customers sells your product to other customer without you needing to spend a dollar on that. And if you will be the company that gives this hope, you have much more sellers that you expect.
What you can do, is to make Lifetime licenses available only if Ubuntu is used. But not other OSes. So then you satisfy the customer who is looking for fully OSS/Lifetime alternative to know that they can be safe, and if needed, they can run a server from their basement at the works case if everybody is kicking you out (despite that you did not break any law, just because you said something different).
2. Ubuntu - please focus on it. That's where all OSS customers are coming now.
3. Secure hosting (VPS). You have to have on homepage a trusted list of hosting companies in EU, US and Switzerland that won't kick you out because of negative comment about hosting company, as well as they would do the work to your server if needed for hourly rate without ZERO BULLSHIT - many hosting company that installs DirectAdmin just sents you on three letters when you ask to upgrade something and to help fix the server if websites are not working after their upgrade (i.e. couple cores added, XHProf, XHGui installed).
Also I cannot find a proper hosting provider that can allow me to create an IMAGE of VPS server before we will upgrade it and to restore it from image if it fails. Amazon has that for a years. I cannot find trusted hosting for DA.
4. Consider providing fine-tuned DirectAdmin+Ubuntu VPS NVMe SSD 4 cores fast and expensive (i.e. 200 EUR/mo) hosting yourself. You can make money as Kinsta.com does. As of now you offer a product, but you don't have any premium provider listed in Switzerland, continental EU and US. When you don't have it, you can't get premium class business status with DirectAdmin. Remember, that WordPress is not just OSS. They also has WordPress.com their own hosting, as well as vip.wordpress.com that host such websites as Techcruch.com. That is already a paved path to success - just use it.
5. Get an investment. Seriously - your company is large enough to get extra money and loose 10-20% ownership of it. But that is not 50%. So it means you will get a lot of money, you will get 20 times more customers, and loose only i.e. 20% of your business. After that you will still be much in stronger position that now.
All we're trying to do here is get the resources to develop further.
