Vendor lock-in is everywhere — Wix, Shopify, no-code platforms, even overly restrictive SaaS tools. If you haven’t written the code, don’t truly own or control the product and data, and can’t deploy or host it wherever and however you choose — then you haven’t actually built anything.
I would say shopify and Wix are definitely useful for quite a few people who wouldn't otherwise make a website.
But for those who are able to do it with other means, giving up freedoms with a vendor lock-in might not be worth it will be my interpretation of this statement
