Besides the obvious trolling occurring here, I'll answer your question on behalf of OP. Arduino was (at one time) considered the holy grail of Makers. They had open source schematics[1] and were very easy to use while quickly prototyping something. For Makers, once the prototype phase had finished and it was time to move to 'production', the ATMega and ATTiny chips were very easy to buy in bulk and use directly in the product, with the guarantee that the code written on the Arduino would (for all intents and purposes) work on the embedded chip. Long story short, before they shot themselves in the foot by infighting, they had a respectable standing among tinkerers and makers.
