Usual response from most of people are their opinion, however even if it meant as something positive, it does not mean that person at the other end will interpret exactly as you intended to. It is already difficult to communicate face to face without misunderstanding when it comes to social media it gets even more ambiguous.
On the other hand it is her life and her children. if she can afford to spoil them then it is her prerogative to do so I guess, but placing it so open on social media is an open invitation for others other to express their point of view... good or bad. Celebrities that wants to constantly stay in the public eyes usually do not care what kind of reaction they cause - they just need any type of reaction from public, to keep them talking.
I can't tell if you commenting or deleting the message was bad or good thing... it is that both of these actions were your choice.
