Apple doesn't lock anyone into messaging apps (they have pretty great system intergration for alternate apps!) - social groups do.

social demographics just use the chat that is closest to whatever they like to do online. iMessage is more of a "it's always there if I need it" thing as I get it, not so much something chosen out of confusion -- the social demographic is quite good at compartmentalizing their lives across many apps.
IMO, the buy-in for iMessage is an iPhone. If you contrast a $429 new iPhone with the buy-in required for other mainstream apps (share and license your private data + metadata with advertising companies in perpetuity), $429 doesn't seem unreasonable at all; but if you prefer to pay with your data instead, all platforms (including the iPhone) provide an option to do so via options like FB Messenger[1] and WhatsApp[2].
If Apple were to remove these alternative options, along with SMS/MMS, and support only iMessage communication - there would be a much better support for the claim that they "lock in" their users.

Most other countries are using some other messaging app, so clearly these aren't super significant hurdles. I agree "lock-in" is strong wording that probably doesn't apply to iMessage. But you cannot argue that iMessage is competing fairly with the likes of FB Messenger / Whatsapp / Telegram / Signal.
