Safe, long-term alternatives to abusive subscription-based models?

Hello,

I’m late to the party but I’ve just discovered that Tobii Dynavox has decided to lock any form of sound (even recording my own voice) behind a ridiculous €120/year paywall. How stupid is that, can you believe it?

I can’t even express how angry I am about this greedy business model. I’ve seen some posts about this here, and that’s why I came to ask for safe alternatives. We have a Proloquo2Go license, but I've seen they now have their own shiny new subscription app, and I seriously wonder if their original software will just be left to die. I know I'm not in a parents' sub, but still, I wanted to get your opinions on how to deal with these subscription-based models. What are you all using that won't hold essential features hostage?

Thank you.

EDIT: I’m not a speech therapist, professional or even based in the US. I’m just a parent of a disabled child, and I thought I would get good advices here. Thanks to all for your answers.
