If installing both helped you, then perhaps that's a good strategy for some. I'm more of a "leave the abusive relationship and cut ties" kind of person, which is why I don't advocate for both at the same time. People often end up going back to the familiar option, rather than trying something new.

As a side note, that's not what a fallacy is. Fallacies are invalid logical statements, and I didn't make any false statements or present any sort of false dichotomy. A false dichotomy would be if I said something like, "You have to choose between Signal or WhatsApp," which is obviously false because you can choose both.

Though again, that's not something I advocate on purpose, due to the aforementioned issue I have with "being the product," and it is not fallacious or deceptive to exclude the suggestion of installing both in light of that additional premise.
