Without making a judgement on weather or not it is or should be legal, it's sadly common to plagiarize or outright copy without conscience amongst marketeers, especially the smaller firms.

I have conversations with (often the same) marketeers that they need to purchase the $9-99 font they've used in their design on almost every project. They send me copy often verbatim copied from the website they are "taking inspiration from". There is unsurprisingly little integrity in the industry. Bigger firms is sometimes slightly better since they have lawyers cracking down on this kind of behavior.
