Great app but I find it hard to trust this company! – iThoughts - Mind Map Review

I just begrudgingly paid the relatively high price of this app. I do believe the app is worth the money for what it does... the problem is that this is the second time I’ve bought this app! I had already paid for the previous version years ago, and I’ve always told myself I’d never give in and pay for it again after what I consider was a shady move making a virtually identical new version and removing the old one... so I now have new devices and no longer have the ability to run the old version, so I bit the bullet and bought it. My question, from one dev to another: what assurance do I have that you wont simply pull the same move and remove this app and force me to choose between downgrading to crippled demo or paying a fee again? I couldn’t even tell you what is new in the app from my now ancient version. Everything is where I remember it, some minor differences, but in large part I see no major revision to the design that would have justified what you did. I will say that this is the best mind-mapping tool on iOS, by far... that’s why I paid again. But it seems unfair, even a bit like a bait & switch, the way you handled this and now got twice the profit out of myself and others. I’d like to know your justification, but more importantly I want some assurance that I made the right choice and will not be left feeling wronged once again! I’d gladly change my review over time if I become more confident, but for now my trust must be earned back.
