The main point I think is if you are doing deals with international customers... bitcoin will be the most convenient way of payment you can ever ask for as a businessman. It is a lot faster and much safer, I believe. People can scam you with fake bank transfers but you are able to see in the blockchain the transaction.
When you are doing your business especially with your trade partners, there is legal thing for consideration on both your side and your trade partner side. You can want to make or receive payment of a business deal in bitcoin but it's up to your trade partner too. If the trade partner does not accept bitcoin by any reason including legal issue, you can not do any business deal in bitcoin with that business entity.
Besides, bitcoin has also become something of a marketing tool nowadays. Businesses are using bitcoin to find the community and invite them to try their products or services.
I don't think any bad thing with this free marketing for Bitcoin to expose it to more people globally. If it is not marketing for scammers on behalf of Bitcoin, it's good and always keep in mind that "Bitcoin is not scam".
