"Get Acrobat Reader" Links - Still Needed?

While browsing a local Church parish website recently, I noticed they had a link to their parish bulletin, in PDF format. I was perplexed, however, by the fact that there was more screen real estate taken up by text and a button that informed me I needed Adobe Acrobat to read the PDF than there was by the link to the bulletin itself!

How is Acrobat Reader as important as the links to the PDFs themselves? That's the message you send to the reader when he sees equal space given to Acrobat Reader instructions as the link(s) to the PDF(s) themselves.
