Be careful when choosing which versions of which licences you use, if you are mixing them with other licences, as this can alter your options if found to be (unintentionally or otherwise) in breach of them. GPLv3 and CC v3 & later licences have a cure provision clause which makes it clear that you can simply stop using the code with 30 days as one of your options to rectify the breach (the other two key options being to negotiate different licensing terms, or in the case of GPL go the GPL route yourself). CCv2 and GPL2 did not have these clauses and this can lead to copy-left trolling as discussed in https://archive.ph/N84oj https://archive.ph/N84oj
