Nope.  No Biblical scholar or leader interprets it that way- only secularists failingly attempting to push an agenda.

Matthew is clear: Jesus openly wishes us to go and make disciples of other nations (a.k.a,*The Great Commission,* if you care to actually know more about the topic).   Jesus is clearly stating that if one has the outward form of prayer only, or if the outward form focuses attention on you, the public acclaim that you receive—real or imagined—is all the benefit you will derive.  Nowhere is that interpreted to mean "pray in private, only."

See you at the next National Day of Prayer  :)
