Actually, you are wrong...the barf alert is for the way the article credits mormons ONLY for being there after Katrina (in their yellow tee shirts) and the further aggrandizement of the mormon history which is not all that stellar.
Have a look at this web site about the tee shirts:

I had problems with formatting from the website, but here is the information, and the whole website is worth reading.

Page 5 Organizers Should Not Commit to Providing Repetitive Services or Financial Resources
Opportunities for Mormon Helping Hands projects come in many forms. Projects that address a recognized
need in the community are generally better received than those that are simply convenient or easy to accomplish.
Take time to think through the potential for good (to others and the Church) before recommending
projects to priesthood leaders. Generally, choose projects that do the most good for needy individuals or for
the community.
Organizers of these projects should always consider building relationships to be an important objective. Projects
completed in cooperation with government and civic leaders generally produce the best results and build
the strongest relationships. Church Humanitarian Services representatives may be a good source for project
ideas and opportunities.
Involvement from third-party sponsors such as large corporations and humanitarian organizations can help
increase the potential for good and the visibility of a project. Also consider that some projects lend themselves
better to photography and videotaping than others.
Examples of Mormon Helping Hands projects from around the world are contained in Appendix B: Examples
of Successful Mormon Helping Hands Projects. Other ideas for projects are listed below. Please note that the
Churchs role in most cases is to provide laborers only. As a general rule, goods and materials should be supplied
by the organization being assisted or by project sponsors; however, priesthood leaders have the option of
using Church resources in appropriate
circumstances.
Likewise, it is important to remember not to obligate the Church to
make financial contributions. Instead, these projects are often funded by private donors, local
businesses, government entities, or the organization being assisted. (For example, goods would be provided by the
organization, and labor would be provided by Church members.)

Now, with this in mind, are you convinced that the aid offered by the mormon church has no strings attached and is just an example of Christians doing good for the sake of their fellow man?
Who pays for (the yellow) Mormon Helping Hands T-shirts and vests?
Answer: Local unit budgets or local members should pay for vests and T-shirts for nondisaster relief projects. When the Churchs Humanitarian Emergency Response participates in disaster relief efforts, a supply of vests and T-shirts is often included as part of the relief shipment....
And, wanna bet that the retail cost of these shirts are included in the dollar amount claimed as "Humanitarian Relief" by the mormon church?
