In addition to the other problems raised, it's frustrating that while Reddit itself continues to be open source [1] with significant contributions from the open source community [2], neither of these new apps are (and with no signs of that changing).
Promotion websites and server-side engines are nice (even though we know Reddit Inc runs a slightly modified version), but malicious client-side apps can be significantly more harmful by abusing permissions.
That's why I'm very careful what I install on my phone: unlike Reddit posts, I have virtually no control over what the software does.
