Anxious attachment dressed as secure attachment...?

I'm dismissive avoidant trying to learn how to be secure, so I started following different media and I noticed a strange thing, I don't know if it's just me, maybe, but something's off - did you notice how social media lately sells anxious attachment as secure attachment? The posts about blocking someone if they didn't respond for a day...I never felt a need to text people that often. EXCEPT, when I was before therapy and extremely anxious. Yet, the "secure" people treat it as a requirement. I don't know if it's coming from my avoidant attachment and it's really how it should be, but that does not look to me like secure attachment at all. That makes learning how to be secure so much harder.
