There are several other collections across the globe compiled from newspaper and online death/funeral entries such as UK and Ireland, Obituary Index, 2004-Current / UK and Ireland, Newspapers.com Obituary Index, 1800s-current
"We work with partners to scour the Internet regularly to find new obituaries and extract the facts into our database"
And you have Legacy.com and Funeral Notices UK, My Family Announcements, Telegraph announcements etc and all the local sites for deaths yesterday.
Many of those announcements, whilst not usually including DOB, list locations to various degrees of preciseness, spouses, children and grandchildren.
The GreyPower info is a database compilation. Dads N.I. death 2 years ago still appears on Funeral Times but has not made its way to Ancestry yet as far as I am aware, likely will though.
One also has the Findagrave 'volunteers' harvesting such sites uploading data

eg

https://discovereverafter.com/ as welll as his parents deaths and 200 year old records and headstone images, many nicely drone mapped to aid finding on a visit.
