In my own mind I phrase that differently. Whether it's gentler or more
stark is up to the reader, but for me it's more:
...it can't address the fundamental differences between desktop
and web architectures, and the limitations inherent in Emscripten.
Emscripten is good for what it was designed to do. But look deeply at
LC, consider what Emscripten is, and the more time you spend pondering
it the clearer it becomes how difficult it is to put a desktop app's
square peg into a browser hole.
"Difficult" is maybe unfairly optimistic. And "impossible" never applies
to software. Perhaps "prohibitively expensive" is fair.

Putting an entire scripting engine and object model into a browser
application that already has its own scripting engine and object model
cannot achieve size, performance, and integration features as well as a
web-native implementation.
If you truly need a browser as your only deployment option, it's kinda
hard to argue against going with the grain of the browser.
But most apps that might make good candidates for LC's HTML export have
characteristics that lend themselves very well to not doing HTML at all,
instead using a one-time download of an LC standalone which then
downloads and runs stack files (a practice that, in the absence of a
more common label, I like to call "streaming apps").
Fits most of the same uses cases, but provides a more focused user
experience that integrates with the OS as only a native app can.
Extra bonus points that they're cheap and easy to build in LC, fast
cheaper to deliver sophisticated works than even web-native implementations.
For the sorts of vertical audiences where LC's HTML would seem
interesting, I believe simply streaming stacks in a standalone is the
most underappreciated and underutilized opportunity in our community.
MetaCard promoted the idea heavily with some nice example downloads, but
in all these years only a few of us make streaming apps regularly.
If you're waiting for LC's HTML to get good, let's discuss streaming
apps for those where they might be a great solution. We really don't
need to wait for anything to have the benefits of net-distributed apps.
You can have it all today, with the LC you know and love already.
