Lief also said "The HF+ is a significant step forward as I have shown in previous videos, but it is not a step big enough to make external filters unnecessary."
That said, We are sure few will be disappointed that it will not outperform units costing 6 times as much. That still makes the HF+ an excellent value.
The great thing about SDR is that most of the magic happens in software, and the HF+ is brand new. There will be many improvements likely while other units may be many years old and all the limits are pushed as far as they will go.
To write that "We are sure few will be disappointed that it will not out-perform units costing 6 times as much" is a red herring. Though, as you've brought it up, as it is, in some situations, the HF+ isn't out-performing a $5 TV dongle.
Anyway, the, very legitimate complaints, are about the HF+ not performing as well as the claims in the advertisements - the very adverts that have since been appended - though are still a gross exaggeration of its real-world performance.
Very poor VLF.
A lot of images on HF

TETRA images on VHF airband.
You're right though. Leif did say "The HF+ is a significant step forward as I have shown in previous videos, but it is not a step big enough to make external filters unnecessary." and thank you Lief for making this very important point. But that isn't what's been said ad-infinitum by Airspy itself.
Youseff, the frontman of the company has made, among others, these claims:
"Sensitivity is unaffected by strong signals".
Since shown to be untrue.
"No external band aid filters are required".
Since shown to be untrue. In fact, everyone is now claiming quite the opposite.That line was actually supplied to all of the resellers and is still present on several of their websites and since removed from others.
With respect (and many know that you are actually an active part of the community and have, in the past, been very helpful to buyers) as you are a reseller, you too are making money from us, Most are more inclined to listen to the Leifs and Adams of the Radio world than those making hard cash from us all.
