We reached out to Proctor & Gamble, the maker of Tide, for a statement on the trend. They said:
Nothing is more important to us than the safety of the people who use our products.
Our laundry pacs are a highly concentrated detergent meant to clean clothes and they’re used safely in millions of households every day.

We have been consistently proactive in providing consumers with the right usage guidance and tools to enable them to use the product safely. Here is a recent video (https://www.youtube.com/watch?v=-JJ-Q45-k30) as an example.
