Actually, Intel is not accused of simply offering quantity discounts which is a long standing practice. It's accused of offering discounts and support to companies that DID NOT use AMD cpu's. The news has also claimed that the EU, Japanese, and Korean FTC's have been communicating, so a multinational company is no longer bigger than the countries it operates in. Especially if it's a US company, since the clout of the US is declining daily.
The laws governing these things were hard-won over decades, are basic to the functioning of a modern economy, and are not going to be changed for some foreign semi company. Intel could have competed 100% and done very well and been very formidable. Instead they apparently chose to go over the line. So far they haven't been fined much and the actions have made money. That may well change - stonewalling is a bad idea.
Being over the line - "abuse of dominance" in the EU - also makes it harder for Intel to enforce its licenses. That wasn't necessary but is still a reality.
