1) No matter what app is used, there are going to be risks. Suggesting a larger company is more secure or less vulnerable is naive at best. Conversely, saying a small company can't provide as good a service and focus is also naive.
2) The perfect app doesn't exist so, stop looking for it.
3) Use what works best with your personal workflow regardless of what others use.
4) Although subscription software is not my preference, there is nothing inherently wrong with using an app founded on such, versus a lifetime license which is usually defined as 5 years in the EULA. A company can be bought out or go under at any time. It is a gamble either way.
5) I think some in the thread look to find fault in every app or situation mentioned while trying to find positions based on nothing more than fallacy.
6) As quickly as tech and threat levels change, what worked last month or last year may or may not be the best to use in the present. Make informed decisions based on the facts before you not hunches or what if based on nothing more than logical fallacy.
7) Open source doesn't mean the software is inherently more secure or less vulnerable.
8) Never rely on any app or company to keep your personal data safe and accessible to you at all times. That responsibility belongs to the end user. Always have a backup contingency.
9) If someone uses an app or website service you don't like or agree with, that doesn't make said person wrong. Our duty as fellow members is to point out any known problems we may know of based on facts, share that information with others, and not get into circular arguments, which serve no real purpose.
