Just because a lot of people do something, doesn't mean that they're doing the right thing. A Golden rule, that applies to all aspects of life.
When I was at school, I used to hear my teachers pronouncing some words in a weird way. For example: Where, what, and when were pronounced as hwer, hwat, and hwen with an 'H' at the beginning. In my case, this was obvious, but in different cases words pronunciation may be a little tricky.

Is it Skype (as in 'pipe') or (Sky-pee)?
Well, it is Skype as in 'pipe'. I don't know why do people use the 'pee' way.
To make sure that this is the correct way of pronunciation, sign in to your Skype account, and make a call to the testing center (a free call). The lady there will say: Welcome to Skype! ;)
Adobe or Adobeee?
It is called 'Adobee', and you can refer to youtube videos about Adobe's products.
At first, I thought that it was called 'Lenix', but last summer i met an instructor that teaches 'Lie-nex' related topics. He pronounced it that way, so i thought that i was mistaken.
Later on i watched a youtube video of Linus
Torvalds the founder of LINUX pronouncing it the right way:

Let's move to 'Giga' & 'Jiga'.
This was tough. I read a lot of articles about it, but i couldn't reach a 100% correct answer.

I read in an article that it is pronounced with a Hard G when used in biological and chemical fields, and with a Soft G (like in 'giant') when used in physics and electronics.
To me, pronunciation is important. If I hear anyone saying anything in a wrong way ,I would correct him.
To some other people, pronunciation is not important as long as they understand what you are saying.
