I have gathered the data from a content creator on Instagram (https://www.instagram.com/loewhaley/) and yes of course the credits are mentioned everywhere about this.
Based on the responses here it seems like what I started as fun activity can be something more than I thought.
I'll be looking into the possibilities of improving the content to make it less satire and more appropriate for most of the people out there.
Since it's an open sourced project (https://github.com/AkashRajpurohit/howtoprofessionallysay), you can share your feedbacks and idea improvements there.
At ending note, I would just like to say to anyone who feels this is really good and I'm going to use this word by word, please don't, take this as a grain of salt and not seriously (atleast at this point of time till I better structure the content) and anyone who feels negative about this, I'm sorry you feel that way but don't take this very seriously.
