This may be wrong or offensive but it is nothing new at all.
I know of many boomers whose parents kicked in on down payments and cosigned back in the 70s when interest rates were so high. I also know many who kicked in for college for the grand children in the 90s. I always marveled at this. First that they could and would do it and second that the children would let them.
Never could and never would were the terms I had.
Why on earth would it be "wrong" or "offensive" for individuals to make their own decisions regarding their families' finances? Can any sensible person be "offended" because another person does something with which one disagrees?
