You're not wrong about the issues involved, but the way you went about it was attacking Backupify, not directly for bad security practices, but indirectly through the "Backupiphish" scare-mongering.
And as for your accusations, you started with setting up a hypothetical company that looks like them and commits massive bank fraud, then saying that it "has nothing whatsoever to do with Backupify. No sir, not at all. Pure coincidence." If you want to make those accusations, back them up. If not, write a post about their bad security practices, instead of a post about a (hypothetical) web service backup company that's (ahem) entirely unrelated's crime.
Gee, so sorry I didn't write the post you would have, and chose to approach the issue satirically instead. You do understand satire, don't you? You do understand how _A Modest Proposal_ was more effective than some dry exposition of the underlying issue, right? Maybe my "wrong choices" about how to raise awareness of an issue are the reason that you were reading my blog and not vice versa. Everybody loves a kibitzer.
Maybe I wasn't clear: my main issue with the post isn't that it approached the topic from a non-factual angle, it's that it does so in a way that looks like an accusation of a very serious crime.
The line at the end isn't subtle, it's clearly sarcasm intended to mean the opposite of what it says, that is, that this post is about Backupify. Well, the post is about a company that provides the same service as Backupify but instead steals bank account details.
