Can-do attitude includes making things that were otherwise annoying frictionless and easy through technology.

The feature being discussed here is literally the ability to manually press a button to send your location to your contact. With the new Android permission model you can even block the app from reading your permissions when not using it.

[In depth answer]

I dug up the RCS5.1 spec [0]. RCS location is not a benign feature where a user is sharing its location every once in a while by pressing a button. RCS location appears to be continuously broadcasted on unsecured channels, open to third party middle men, for example Google, Verizon or three letter agencies. Note the last bullet point, "Geolocation". Perhaps I'm reading this wrong, and this is not yet another veiled attempt at commercial surveillance. Please educate me.

From Section 3.7, Social Presence Information:

===

In the EAB, the contact information is extended with social presence information and foresees the following attributes:

* Availability, indicates the user’s (un)willingness to communicate,

[snip]

* Geolocation, depicts the user location

[snip]

Once User A has accepted User B as an RCS authorized contact, User B will be able to see the geolocation information of User A (displayed with a text or a map, or both of them) and all updates of that information.

The section you have listed is about "you have set a geolocation already, control access to who can see it".

Frankly there is no way that Google's RCS app streams your location to any endpoint without an explicit opt in in the app. I'll eat my hat if I'm wrong.

User selects to share location with 1 person in the world, and maybe even forgets about it because the feature is such low value [for the user] anyways. Google [and Verizon, and whomever else is in the middle] gets to snoop on user location forever at whatever precision they want, because "it's in the spec". Looks like a dark pattern for tricking everybody to share the location with Google, enabling corporate 24/7 mass surveillance.

Shameful.

Google has many choices: don't implement clear-text geolocation presence, don't implement RCS, speak up in the standards committee, communicate the implication to Google users, etc. Google chose to silently use a dark pattern to enable 24/7 location snooping.

Shameful.

You are literally looking at what the spec could allow a compliant client to do and then assuming that Google will make an app that uses dark patterns to trick users into doing them when they don't want to (and when it also provides no real value to Google compared to the data collection they can already do)

This is the core dark pattern of BigTech:

"Share with your friends" means "Share with your friends, and we'll snoop/aggregate everything that's ever shared by anyone using our platform in perpetuity and use it to subvert your will, haha 'private communication' is so XX century".

RCS is yet another excuse to implement this dark pattern, with explicit provisions to include unencrypted 24/7 geolocation information in it. Google just rehauled their Android messaging strategy around RCS. They deserve to be called out on it.

PS. You claimed "The feature being discussed here is literally the ability to manually press a button to send your location to your contact." Until you take that back as factually false [it's continuously sending, not gated by a button press per send], we're done here.

A. The ability to manually press a button to send your location to your contact

B. The ability to manually press a button to send your location to your contact without man-in-the-middle snooping.

All I'm saying is that B is better than A, for me personally and for our society at large.
