Read receipts are just as much of a social anxiety trigger for me; “oh they read my message, why haven’t they responded” or “they read my last few messages, why didn’t they read this one, am I boring them”. I turned those off entirely. Sometimes new acquaintances ask me why. I tell them it stresses me out and makes me overthink social interactions. Most people are amenable to this explanation.
Yeah, for me as well. Although for me, it's not because I wonder why someone hasn't responded... it's because often I'm in the middle of something and don't feel like responding right away, and I get overly concerned that the other person will think I'm being rude! So I don't use RCS with anyone besides my girlfriend. But there's an implicit agreement in it that we try to get back to each other fairly quickly. Neither of us wants the other to think we're up to something sketchy. This helped ease me into our new non-tracking reality.
As a side note, one other reason I developed such severe distrust along with the location glitches was that occasionally some of my SMS texts simply never went through to her. This led to a situation where I thought she just ignoring them, so I'd just feel kinda shitty and leave her alone, until we finally went through our chat thread together and realized she'd never gotten them.
Same here. On my WhatsApp, read receipts and online status are off, and have been since I first found the feature. The way "they left me on read" has found its way into common English is disturbing.
