terms of use

I think you’ll find there are similar clauses in pretty much all legal agreements. Check your broadband supplier’s T’s and C’s and there’s probably something excusing them for not providing internet access. Check your Microsoft licence and see what they can opt out of. 
As you say, many of us are more cautious at the moment, but at the end of the day you sign up to it or you don’t use the product. 

same for me, I didn't ask for anything, the update was done automatically, even if it was strongly desired in view of all the shortcomings !!!!!

I find certain terms and conditions shocking, like those mentioned above, or even a ban on using products under 16 years of age without parental or guardian consent ....

To my recollection, I have never had to accept such conditions to use SONOS products.

If we don't want to accept, we can no longer use our products, will SONOS reimburse us for them then? These clauses are new and were not present at the time of purchase and god knows how expensive they are!!!

You’ve actually no idea what the Ts & Cs said previously. And you will have accepted them. I would bet my house on this clause being unchanged - it’s just been brought into focus by the recent app furore. 

I assure you that you had to agree to the terms of use (aka the EULA) when you first installed Sonos.  It’s standard for almost all software.  The part about age limits has been there as long as I remember, and I go back to 2008.  As to getting reimbursed, not a chance.  You don’t own the software, you license it, and it’s pretty standard for the EULA to change (and those changes are protected by the language therein).  There are exceptions, like if Sonos suddenly changed their privacy policy to sell your data when they previously promised not to, but I see no evidence of that. 

I admit I don't remember accepting all this.
As the topic creator says, why not highlight the changes? We are forced to accept new conditions ??? which ??? if we don't accept, we are blocked and we don't know how to do anything anymore !!! Would that please you ?

In short, it's been a month since for some people their installation became unusable... a month!!! ... and, in fact, these new conditions give the impression of shielding themselves against any recourse against their incompetence.

I’m more than happy to accept their generic terms if it means I can play music on the speakers.

You either accept them or you find an alternative audio system. You don’t have any choice. Sonos is in charge of their software and hardware, not us.

There might be additions to give extra protections if they make future errors, but given no-one is taking any legal action against them anyway, I suspect it simply tightens language rather than getting you to hand over your first born child.

ok for the first part, not for the second ....

If you buy a car and then suddenly the brand decides to force you to accept geolocation otherwise your car won't start, it's not fair!!!!

do you find it normal that they force you to agree to share your data? that they prohibit you from doing anything as a recourse (who would) in the event of a breach, removal of services or features??

Where have they forced you to share your data? This is specifically something Sonos doesn’t do. Anonymised usage data is as far as it goes. 

If I bought a car and they changed a fundamental of my original acceptance, then you would be within your rights to return the car. But you have provided no evidence of anything fundamental that has been changed in Sonos’ Ts & Cs.

And they are not forcing you to accept a broken system - they are working on fixes, and have been demonstrably doing so for the last four weeks. 

Unless you have not bought anything or created an account for anything in the last 20 years, then caveat emptor is nothing new. 

See, that’s the thing, you didn’t buy the software like you buy a car.  So stop making comparisons to something you purchased, they just don’t apply.
