Well, When you say such statements, it means that you have accepted the loss even before the start of the match/series and losing a series doesn't matter to you. I don't think such statements would do any good to the Bangladesh team. If the Bangladesh team come for sight seeing, why the Bangladesh cricket board is paying the players for tourism only

I haven't read that full statement yet, but if anyone from the Bangladesh camp said this statement, it is highly irresponsible and that person or the team should be held accountable that they are wasting the nation's money that is being spend on the Bangladesh Nation cricket team.

I think you need to understand few things before having any objection difference of quality is widening and teams like Bangladesh, Zimbabwe and West Indies completely out of shape due to this difference here ICC needs to work out and bring tier system which will help them for increasing quality and bringing good entertainment for fans.
Countries like Zimbabwe and Bangladesh taking huge funds for development of game but nothing happening mostly these funds are going in pockets and corrupt peoples are doing their tricks which are never been helpful for game Bangladesh is well populated country where cricket is having good scoop but needed strong and good management to handle things, but they fail to do, and now they are on bottom of all rankings.
So in this case, the corruption is not only at the cricket board high officials but at the every level. Those who have guts to say such statements suggest that they are so powerful that even after these statements no action could be taken against them. They are fearless people.
Also in that case, ICC could not do anything or interfere in their internal affairs. They can only grant them the funds to improve their cricket infrastructure and arrange them series to play and in case there is no progress and the funds not going in the right place, they can just not fund them anymore.
