Actually Chilli gave a good explanation in other thread
1) Bheeshm knew that Karna was Kunti's child and it's clear that Kaneen children and their mothers weren't respected in the society. Now think of it, what opinion would Bheeshm actually have had of Kunti?? Wouldn't he think her to a woman of lose character? Why would he want the children of the woman of a lose character (only hers remember they weren't the children Pandu biologically) on the throne
2) The birth of Pandavas can not be compared with the birth of Dhritrashtra/Pandu as many people wrongly do because firstly Ambhika and Ambalika weren't woman of lose character, secondly Dhritrashtra and Pandu were still Satyavati's biological grandchildren since Vyas was her son(Bheeshm's oath was to ensure that Satyavati's lineage is on throne, he didn't say that Satyavati+Shantanu kids would take over), Pandavas on the other hand were only legal lineage of Satyavati and lastly while Satyavati asked for Bheeshm's permission before sending her DILs to Vyas, Kunti+Madri did it without his permission.
Now tell me who would be preferred by Bheeshm here? Pandu's Kshetraj son by a woman of lose character or Dhritrashtra's biological son by a chaste woman (chaste and characterless not by reality, but by just how Bheeshm would view them)
3) Duryodhan was born in front of Bheeshm, he was among the ones to raise him since birth, Pandavas joined him at the age of around 7-8. For whom would one feel more? Just think of it.
4)Did it ever occur to you why Duryodhan always thought that the kingdom belonged to him? Why he was so staunch against Pandavas since childhood?? Someone has to instill this feeling into him right. Who would have done that? Shakuni? Was Bheeshm so stupid that he would let a person who is spoiling his grandson stay in his territory? And despite Dhritrashtra being the king till this time Bheeshm held great power
5) Karna knew that Kunti was his mother (he says this to Krishnaji when the latter approaches him) who would have told him. Especially since Bheeshm knew it? And when did he get to know about it- Was it at Pandavas childhood? This would actually give a reason why he hated Pandavas so much.
6) Could Duryodhan, a kid plan out for the Poisoning of another kid and no one including Bheeshm getting to know about it? Bheeshm wasn't some cry baby like BRC made him. Shakuni was just a guest and Karna at max a servant/bodyguard by then, their support wouldn't have helped planning the murder of a prince. Aside why didn't they ever complain about such murder attempts unless they were sure that they don't stand much chance of justice.
7) Why did Vidur ask Pandavas to remain hidden after Varnavrat, they had the public support then, they could have challenged the wrong doers, but no they only got confidence to return after marrying Draupadi and gaining Panchal support. Even then they were given the barren land filled with robbers and infiltrators (i think Danavas and Nagas had infiltrated into those areas and KhandavDahan was aimed at freeing it) Not just that before the Rajsuya, they were still like Hastinapur's protectorate (so before the Rajsuya Yudhishtir's standard was at par with Karna or Ashwathama) Duryodhan was like an overlord to all of them. Why would an all loving Bheeshm let all this happen?
It is highly probable that Bheeshm actually wanted Duryodhan to become the king, but he could not openly tell this because the Kaunteyas had the support of the sages, Yadavs were gaining some dominance and public had sympathy for these kids. They would have been killed had their spy Yuyutsu not supported them.
Shakuni and Karna probably were just the front line minions for Bheeshm to ensure Pandavas are removed from equation without his hands getting dirty
