Some of these are acquires so it's hard to argue the money was 'burned'. That said I do agree acquired companies can be viable as the product usually gets put on life-support or ruined/shutdown (like Club Penguin)
Even the products got eventually shut down I still don't think the money was necessarily 'burned.' Most buildings eventually fell or got destructed so were all the resources spent on construction burned? But whether a product actually helped the users is a question too nuance to ask.
A lot of acquisitions are tech and talent and the details matter. A startup that gets acquired for $30M after burning $70M is definitely burned.
