If T20 is not real cricket (which is not of-course) then how are we going to label T-10 and T-6 if they ever play it internationally. May be we will not see cricket then, we will see baseball or this kind (I don't know how they play baseball but seen them to hit the ball hard and run LOL, the ball don't even need to pitch :-P)
Real Cricket or not this comparison only comes at play when spectators/players think T-20 is a real form of cricket and judge any player skills only basis of shorter format, which is very wrong. For example: Make a team of all Big T-20 specialist players who think they are great players and put them against any County or Ranji team. I can bet you local teams can beat the shit out of them in Real Cricket any day of the week.
For international adoption or eyeballs, ICC is trying to get cricket into the Olympics. That's why ICC granted T-20I status to all 104 members. For only this reason, T-20 is very important to world cricket. But I think that even T-20 Format is long for Olympics (its another debate). May be T-10 looks okay.
You are right we need to promote Test and ODI but greediness never want to promote these formats because they have more revenue in T20 and our jokers can perform better in this format as they have better income in very less time like soccer even now ICC is also not able to do any work in this issue as powerful boards want more revenue and its belong to T20.
Its more of adopt or die situation for all Cricketing boards.
I will talk about BCCI perpective ;
1. India is very big country and has 35+ domestic teams + Under 23 +under 19 +Under 16 .
2. More than 10k professional cricketers (including retired) BCCI has to take care of their salary.
3. Pension plan for retired cricketers. here they are waiting for
Pension Hike 4. No government help in regards of infrastructure. ( In England and Australia local gov takes care of it according to my knowledge, plz correct me if i am wrong)
5. BCCI organise 800+ matches in one year ( Test series + ODI series + T-20 series )
That's why BCCI needs regular flow of money. as you already know how ICC reduced the BCCI's share (around 200 million) recently.
Now about Promoting Test cricket Again India's perspective; Indian cricketers gives Test cricket highest priority. in last 2 years Virat, Bumrah, Shami skipped couple of ODI and T-20 series only because of Test Match. so its depends on players too.
