You need to keep in mind that the web is moving towards HTTPS for privacy reasons. Google is already weighting SSL web sites higher than non-SSL in their search results, and we are only a few months away from the big web browsers throwing all kinds of scary errors when visiting non-encrypted sites. If Acu-Rite is using web-based technology for their uploads, it is probably a good thing that they are ahead of the curve with moving to encryption.
The side effect of this decision for a tiny subset of their customer base trying to man-in-the-middle sniff packets for alternate uses are locked out of the data flow. AFAIK (with a disclaimer that we don't know what the Elite will do) they are not encrypting the OTA packets, so rtl_433 can easily dis-prove the tin foil hat conspiracy theory.....
