Are we being taken for hams?

I suggest you cease whining about it, sell your Sonos (it does very well in the second hand market) and move on.  Not every company is a perfect match with every consumer. 

Good luck with whichever system and trustworthy company you decide to go with, which better meets your individual needs.  As @jgatie says, Sonos isn’t the right product for everyone.

Oh yes, don't worry, as soon as I find the perfect solution I will leave the sonos ecosystem.

It's really distressing not to be able to recognize that some things are aberrant. In fact the Sonos community is as bad as the Sonos team itself. A bit like Apple's in fact, as soon as you criticize their fetish system. And don't get me wrong, I'm as much an Android fan as an Apple fan.

Oh yeah! Another aberration from Sonos! I was forced to take an iPhone to use Trrueplay! I knew it from the start, don't worry, and I first used a friend's iPhone to set up Trueplay. But when you have to reconfigure the system several times in a short period of time, after a while it was better to get one instead of bothering my friends.
They are not able to offer a universal microphone for all users, or AT LEAST market it to satisfy everyone. No, more bad faith! 

Anyway, good continuation to you gentlemen :)

And my best wishes to you. It has been an enjoyable discussion. Thank you for your original and perceptive observations .

I think you’re wrong here, @Nyvek   Many of your points in your original post were wrong, and this was explained to you in answers above. Certainly there are some very strong Sonos supporters on these threads. They know the products well, and are keen to correct false information, as has happened here. How you interpret that desire of theirs for accurate information to be seen in posts is your opinion; I see it differently. 

When it comes to purchasing kit, there is an onus on a buyer to check a product meets their requirements before purchase. To hope/expect features will appear later is naive optimism. Still, your Sonos product ownership has helped you cement ideas and product features for your future needs.
 

Perhaps you could let us know what you choose once you’ve done your research?

Sonos has never in it’s entire history adopted every standard out there like other companies.  They did not adopt bluetooth.  The used optical instead of HDMI passthrough.  The didn’t adopt DTS till recently.  They didn’t do hi-res till recently.  And many other features.  People have been predicting Sonos doom for lack of whatever, for ages.   I don’t find it distressing at all.  That’s not to say that I don’t recognize that features are missing, and some of them I wish were there.  Lack of DD+ and previous gen Beam is not at all high on my list.

After a lot of research, and depending on what I would like, I think I'll go with this:

- YAMAHA RX-V6A amp for decoding, HDMI connections and physical center channel.

- 1 x central to define (like CHORUS CC-700)

- 2 x YAMAHA MUSICCAST 20 to connect in wifi for the surrounds.

-> I would use my Behringer A800 as a power amp to feed my 2 Apogee Centaur Minor that I could connect to the Yamaha pre-out for the front channels.
I would connect my SVS sb-12nsd to the Yamaha.

NORMALLY, I should be happy. The resale of the Beam 2, Sub 3 and Symfonisk + my home player RPI + Allo piano 2.1 + reclocker with Moode audio as well as the FX Audio preamp should cover the expenses.

Don't blame me for my criticisms about Sonos, it's still an excellent solution but lacks some (sometimes very basic) functionality for ME. And that was my gripe (I got tired of spending on an HD Fury Arcana to make up for the audio latency, then an iphone for trueplay, then the Beam 2 for DD+ decode etc... even though I failed to do some research.
