I double checked at our reseller, "Web Host Edition VPS", is not limited
I'm sorry, you're completely correct. Plesk is the only professional panel which has a VPS only license and I looked at the wrong place. I looked by accident at the Web Admin Edition. The VPS editions are cheaper than those from DA.
As for the GUI and users, it's indeed better to agree to disagree, we probably have different experiences with this.
are there really so many people running nulled DirectAdmin licences ?
No as far as I've understood it's mostly the illegal reselling of internal licenses.
now it is the high price luxury prices product.
Not really, it's still cheaper than the other 2, except for the seperate VPS edition of Plesk. For LLH's yes it's now becoming very expensive, that is true.
5€ / month is more in a "possible things" realm.
Agreed to that, however lots of datacenters already asked 5/month for customers to get DA on their vps or server. But this still is 60/year, not 49. Peanuts indeed. It would indeed be a lot more fair especially to multiple licenses holders as there is no pause option anymore in this case.
The reason of the cheaper internal license system is to get datacenters to spread them, make users known with DA so users would buy/lease DA themselves too. However, that was a bit of a wrong assumption probably.
Because why should users buy a license for more money, when they can have a server in a datacenter for 5/month or even for free?
Lifetime licenses are nice to begin with, but as a company one should not sell too many and stop in due time, or at least clearly state that a lifetime license can be declared end of life (like vBulletin did for example).
For us this new model is also way too expensive, but that is mostly (not completely) due to the fact that there is no pause option.
We have 7 external licenses, mostly 3 are used, sometimes 4. But you have to keep paying for all of them to keep the offer.
This would mean 3 not used licences at 180/year = 540/year down the drain. Add up the 4 used at the moment is 720/year.
Total prise raise in fact is then from 0 to 1260/year. We smaller company's can't afford that.
I understand that it's more for big company's with internal licenses.
I think most of us are prepared to pay some amount of money, but this is way to much. And this raise for us from in this example 0-1260/year is the reason that a comparison to current normal monthley prices is just not fair, at least not without pause option like we have now.
Even with pause option it's a raise per license in use from 0-180/year which is still a lot. 100/year would be a lot better and then with pause option.
some providers are still able to bundle it for free with every 2$ vps they sell
I've seen VPS systems for those prices, but none with DA or with enough resources to use DA. I've seen cheap VPS systems but as far as I could see all DA licenses sold or given out with them, are internal lifetimes, no modern licenses.
If they would be modern licenses, then they are most likely nulled questions as DA won't deliver them that cheap to anybody.
I hope DA will look into your argument because now they don't loose money, but with low prices on conversion/upgrades, they have the option to earn a lot of money. You are surely correct with that fact, the lower the price, the more chance people will use an upgrade option.
who knows
