Bert,
I'm in agreement with what you say. I find nothing you mention as controversial.
I have purchased a license for Amazingcharts several years ago. In fact, I believe my practice is one of the first 10 that paid for this program, if I am not mistaken.
Yes, Jon does have the right to make this into a subscription program! If he converts it into a subscription program, it should be made clear that this is a subscription program (rather than hide that fact in the EULA). There should be a grandfather clause (or some consideration for exchanging a permanent license to convert to subscription software).
The website advertising Amazingcharts indicates that this is not a subscription service. All of the reviews on AC on other magazines indicate that Amazingcharts is NOT a subscription program.
But the EULA, the legal backbone to the software, is confusing. If you read the current EULA, it does not sound like anything in the main Amazingcharts.com website. There is a disconnect. The EULA indicates that one can have his license pulled for a variety of vague reasons.
So, I submit to you... if I pay for an update, is that a tacit agreement of submitting to the subscription model... or not? And, as purchaser of a program (or a leasee of this program) shouldn't I be let known if I am downloading a doomsday feature in the program?
I don't think that anyone here is asking for the moon. We want reassurance that we will be treated fairly and there consistency. I really agree with all that you say, Bert!
