Alibaba is definitely not Wawak and definitely not the same company with a different name.
Alibaba *is* a step above Temu (and Wish), but it and those are nothing more than marketplaces for overseas goods without validation of the products. Alibaba is a mega marketplace on the order of - or larger than - Amazon, that provides a marketplace that sells everything under the sun worldwide. It is not a sewing supply company (although some of the wholesalers that sell via Alibaba might sell sewing related items)
This is
Alibaba. It is a multi-billion dollar commerce entity based in China (as are Temu and Wish).
YouTube is not a reliable source of information on these sorts of things.
Wawak and Paccana are legitimate sewing supply businesses.
