Ask HN: Do you think Apple is using iMessage info for advertising?

I have had a few situations where I have discussed niche things via iMessage exclusively and then received similar adverts. Most recent example is a conversation making fun of Air Fryers and toasters. The following day I received an advert in instagram for a portable pizza oven which I have never seen before.

There was another example as well. I understand this is anecdotal and possibly coincidence but it has happened twice. Its not as though I used Facebook or Gmail and I never Googled the product.

What do you think?
